Executive Summary

Suspense is the engine of the screenplay, driven almost entirely by a sound-based predator that can mimic voices and learn patterns. From the 1944 prologue to the finale on the blast mast, the script keeps the audience in a near-constant state of anticipatory dread by alternating moments of quiet strategic planning with sudden, violent attacks. The strongest suspense comes from the writers' understanding that the creature is not just a monster but an intelligent, adaptive hunter, which forces the characters to improvise in ways that continually reset the audience's expectations. The film's most effective suspense beats—such as the catwalk crossing, the trestle collapse, and the summit hatch sequence—are built on specific physical constraints and a ticking clock that make the tension feel both inescapable and earned.

Usage Analysis

• Scene 1 establishes an entire system of suspense in miniature: a sealed door, voices of the dead, and Voss's order to weld it shut. The audience learns immediately that the story's central threat is built on withholding answers while raising questions, and that suspense will come from the gap between what is behind a barrier and what the characters are willing to admit.
• Scenes 4–5 escalate suspense through the inspection camera: the crackling 'That's playback' and the violent tug-of-war create a slow burn that explodes into Bryce's abduction. The screenwriting uses the physical limitation of a camera cable and a narrow drill hole to make the audience feel unable to see the whole threat, which heightens every subsequent sound.
• Scene 10 uses a hidden 1944 door and the grease-pencil warning 'DO NOT ANSWER THE VOICES' to create a layered mystery. The suspense is doubled by a radio call from Noah saying a man claiming to be Bryce is at the control room, forcing the audience to wait across a cut while two threats (the creature and the identity of that man) converge.
• Scene 16 is a master class in object-based suspense: the trembling washer, the one-at-a-time crossings, and the THOOM of the damper used as Noah's counting mechanism. The audience is given a clear physical rule (vibration carries) and then watches the characters try to exploit it, which makes every footstep a potential death sentence.
• Scenes 31–32 intercut three timelines—Mara on the catwalk, Rourke in the snowcat, and Noah in the staging area—creating a spatial suspense where the audience knows all three threats are about to collide. The avalanche is both a rescue and a weapon, and the suspense comes from not knowing who will be under it when it fires.

Critique

• Suspense is used effectively to maintain momentum across a three-act structure: the first act keeps the threat hidden, the second act introduces its rules, and the third act weaponizes those rules. This creates a consistent escalation where each suspense beat teaches the audience something new about the creature, preventing fatigue.
• The script sometimes sacrifices character-driven suspense to plot mechanics. For example, Rourke's phone buzzing on the catwalk is a convenient device to force a crisis, but it feels less organic than earlier suspense beats that grew from the environment (like the washer or the damper).
• The 'one hour' delay Mara imposes on Rourke in scene 3 feels like a standard deadline, but the script wisely raises the stakes by later making the rescue effort itself a potential release of the creature into the world (scene 21). That transformation of 'rescue' into 'danger' is a strong suspense move.
• The finale's suspension of belief is tested by the creature's ability to survive an avalanche and still climb a ladder, but the suspense remains effective because the creature's persistence is tied to its biology (echolocation, learning) rather than supernatural invincibility. Still, the audience may begin to expect the monster to always come back, which risks numbing the tension.
• Suspense between the major action set pieces is sometimes padded with repeated scenes of the group moving through corridors and hearing echoes. While this builds atmosphere, it also dilutes the impact of the more concentrated suspense sequences. The middle act could be tightened by limiting the number of false-alarm sound cues.

Suggestions

• In scene 16, consider giving Rourke's phone a narrative reason to buzz—perhaps a message from his estranged daughter that he has been checking repeatedly—so the interruption feels psychologically motivated, not just a random vibration.
• For the catwalk crossing in scene 16, introduce an earlier, smaller vibration event (a distant train or fan) to prime the audience to the rule, so that the washer tremble becomes a legitimate cause for alarm rather than a sudden environmental coincidence.
• In scene 21, the revelation that claw marks continue upward is a great suspense beat, but the script should make it more visual—a tight shot of a claw mark next to a boot print, or a faint scratching sound directly above—so the audience feels the creature's presence before the line of dialogue confirms it.
• The side branch Rourke points to in scene 21 is given a single line of dialogue, but it could create more suspense if Mara actually considered it briefly, glancing down the dark tunnel, hearing a distant sound, and then rejecting it. A moment of hesitation would make the choice feel riskier.
• The final avalanche trigger in scene 32 is well set up with Calder's radio check, but the audience needs a clearer countdown. Adding a visible timer on Calder's screen or a verbal 'we are go in ten seconds' would increase the suspense of whether Rourke can escape before the shot is fired.

Questions for AI

• How can the suspense of the inspection camera scene be extended so that the audience feels the crew's curiosity is overriding better judgment without making the characters seem foolish?
• Is there a way to make the middle-act corridor scenes more suspenseful by varying the rhythm, such as alternating short scenes of silence with sudden bursts of sound, rather than a continuous slow stalk?
• How can the suspense of the summit hatch sequence be intensified by creating a counter-clock that is independent of the creature's attacks, such as a rescue team that is minutes away from firing an avalanche charge?
• Does the script's reliance on sound-based rules (vibration, echolocation) risk becoming too mechanical, and if so, what nonlinear or instinctive behaviors might add unpredictability to the suspense?
• How can the audience's anticipation of the creature's next attack be maintained in scenes where the group is planning or resting, without relying on false jump scares or repeated echoes of stolen voices?

Executive Summary

Fear is the screenplay's dominant emotional color, and it is built less on gore than on the primal terror of a predator that can steal the voices of loved ones and lure its victims into darkness. The script uses confinement, sensory distortion, and psychological manipulation to create a deep-seated unease that persists even when the monster is off-screen. The creature's design—an eyeless, feline-bodied, almost-human-handed nightmare—is effective because it is familiar enough to trigger mammalian fear responses and alien enough to avoid easy categorization. The most successful fear beats are the ones that make the audience worry not just that the characters will die, but that they will be deceived into walking toward their own deaths by the sound of a friend or family member's voice.

Usage Analysis

• The opening scene immediately establishes fear through the voice of a dead man, then a woman, then a child, and finally Voss's own voice. This escalation shows that the creature does not just frighten; it exploits the deepest emotional vulnerabilities, which sets the tone for the entire film.
• In scene 11, the reveal of the creature using Bryce's body as a puppet—'I'm okay' spoken with honoring his dead brother's name—is a moment of pure horror because it combines physical revulsion (the pale forelimb, black claws) with emotional desecration (a corpse used as bait).
• The sound design described in scenes 13 and 20 gives fear a tangible mechanism: a creature that found a microphone and can broadcast a voice pleading for help. The layout of the tunnel, with speakers and ducts, turns every public-address system into a potential trap and creates a distributed fear throughout the entire setting.
• Scene 26, where Walt is alone in the vent chamber, uses Margaret's voice to evoke fear inside grief. The audience fears for Walt not only because the creature might kill him, but because the creature will use his dead wife to cripple him emotionally before attacking. The line 'She called me Walt' shows how fear and grief become intertwined.
• The creature's ability to learn—in scene 16 it learns the team's decoy pattern; in scene 34 it learns the horn—means the audience cannot rely on any single survival trick. This creates an escalating fear of an intelligence that is always one step ahead, which is more terrifying than brute strength.

Critique

• Fear is used effectively to differentiate characters: Pete is vulnerable to hope (believing Bryce is alive), Rourke is vulnerable to guilt (his daughter), Mara is vulnerable to her son's voice, and Walt is vulnerable to Margaret's memory. This makes the threat feel personal and multiplies the fear across the ensemble.
• The script sometimes overuses the 'unseen voice calls from the dark' device. While effective initially, by scene 33 when the creature picks up the radio and says 'Noah,' the audience has seen this trick so many times that it has lost some of its power. The fear becomes expected, which reduces its impact.
• The creature's visual design—explicitly described in scene 34—is strong, but its reveal happens relatively late. While the mystery is part of the fear, some viewers may feel that the build-up is too long and the physical appearance is not disturbing enough to justify the level of dread the characters feel. The descriptions of the throat sacs and hand-like paws help, but the payoff might be stronger if a partial glimpse of the face or limb appeared in the first act.
• Scene 6's avalanche and portal burial are designed to create fear of entrapment and suffocation, but because the threat is a natural one offset by a supernatural predator, the two fears compete. The audience may be more worried about the monster than the CO2, so the carbon-monoxide countdown in scenes 24 and 25 is less emotionally gripping than the sound-based dangers.
• The emotional fear of a mother losing her child is a powerful subtext throughout, but it is only explicitly stated in moments like Mara's 'You're my son' and Noah's final 'Don't lose it. You.' The script could integrate this fear more consistently into action scenes, such as Mara's panic when the creature grabs Noah's leg in scene 16 being described more viscerally.

Suggestions

• Consider adding a scene in which the creature not only imitates a voice but also inverts a character's assertion—for example, Mara saying 'We're going to make it' and the creature repeating it as a taunting question—to demonstrate that the creature understands the characters' hopes and is using them as tools of psychological fear.
• When the creature is temporarily defeated in scene 32, the audience should feel a false relief that the danger is over. The script can strengthen this by giving the group a moment of genuine calm—a shared breath, a joke, a sense of victory—before the creature claws out of the avalanche debris.
• In scene 26, Walt's confrontation with Margaret's voice could be even more terrifying if the voice recounts details that only Margaret would know, such as a specific promise Walt made on their first date. This would make the creature's mimicry feel like true predation of the soul, not just sound reproduction.
• To avoid overusing the voice mimicry in the final act, give the creature a new behavior in scene 33—such as silently waiting near the blast mast and using the radio to lure Noah—rather than simply repeating dialogue. That behavior is already present, but the scene could be extended to show the creature manipulating the radio with its hand-like paws in a deliberately intelligent way.
• The fear of quarantine—the creature being released into the world—is a major stake introduced in scene 21 when Mara realizes the rescue team's drill would open the summit hatch. This fear should be amplified earlier, perhaps by having a marine or wildlife expert explain what would happen if an invasive apex predator escaped, so the audience roots not just for the characters' survival but for the monster's containment.

Questions for AI

• How can the voice mimicry remain terrifying after the audience has learned its mechanics, and what new variations could be introduced after the mid-point to avoid numbness?
• Is the creature's physical form described with enough specificity to create the same fear in the reader that it would on screen, and what one additional feature could make it more viscerally disturbing without becoming grotesque?
• What is the most effective way to balance natural disasters (avalanche, carbon monoxide) with supernatural horror in a way that makes both feel equally threatening?
• How does the fear of losing a child—Mara's primary anxiety—manifest differently from the fear of death, and can those moments be separated visually or through sound design?
• In the scene where Walt faces Margaret's voice, should the fear be that the creature is impersonating her or that it is actually communicating with the dead, and what does leaving that ambiguous do to the audience's unease?

Executive Summary

Joy is deliberately sparse in this screenplay, appearing only as faint glimmers of warmth and brief pauses in the storm. The script uses these moments to humanize the characters and make the surrounding darkness harder to watch. The most effective uses of joy are the small, earned connections between Mara and Noah—a joke about exploding phones, a promise of burgers, a shared smile in the center of a nightmare. These moments are not just levity; they are the emotional stakes that make the audience terrified of losing these people. The final scenes shift to a more pronounced relief and hope, but even that joy is layered with mourning, keeping the tone grounded.

Usage Analysis

• Scene 2 establishes the mother-son dynamic through dry humor: Noah's 'Your phone will explode if you don't touch it for a whole meal' and Mara's 'Maybe then it’ll pay for college.' This joy is the ordinary, familiar kind that immediately makes the audience feel protective of their relationship.
• Scene 3 adds a touch of workplace comedy with Walt's 'Look what the storm dragged in' and his fist-bump rejection, which is both awkward and affectionate. The tiny laugh from Mara's 'Now you're twelve days and one hour behind' breaks the tension of the scientific debate and gives the audience a mental rest before the terror begins.
• Scene 15 contains a small moment of warmth disguised as an argument: Noah's 'I'm the only one who can tell you when a voice is wrong.' Walt's hidden smile and Mara's reluctant acceptance create a minute of humor amid the gear-up, showing that even in mortal danger, the family can still banter.
• Scene 27 has a visceral spike of joy when Noah uses the emergency bell to drive the creature off the cage and Mara kisses his hair before she can stop herself. The joy is involuntary, a mother’s instinct as much as an emotion, and it creates a powerful release after a long action sequence.
• Scene 35 is the emotional payoff: the storm breaking, Noah running to Mara, their embrace, and his complaint about terrible advice. The joy here is not comic but cathartic, rooted in relief and reunion. The scene allows the audience to exhale, and then immediately undercuts it with Mara's wince and the memory of those lost.

Critique

• The script wisely does not try to shoehorn joy into the middle of monster attacks, but in doing so it can make the first half-hour feel almost too comfortable. The audience knows a horror film is coming, and the extended banter in scenes 2–3 might have benefited from a sharper joke or a small disruption to prevent complacency.
• Joy is mostly confined to the Noah-Mara relationship, leaving other characters under-served. Walt's humor is present but thin; Rourke's cynicism never gets a beat of warmth. A brief moment of unexpected kindness between enemies (for example, Walt sharing a flask with Rourke) would have deepened the ensemble.
• The scene 27 kiss on Noah's hair is a lovely joy beat, but it is undercut too quickly by the cable fault. This is effective for suspense, but the script could give that joy slightly more room to breathe by inserting one more moment of genuine relief—for example, everyone in the cage laughing in shared adrenaline before the jolt.
• The final diner scene carries a clear message of 'we made it,' but the joy is almost too restrained: Mara silences a call from Incident Command, sets down Walt's key, and says only 'To infrastructure.' The audience may wish for one more overt moment of gratitude—Noah putting his head on her shoulder—rather than having the emotion remain exclusively in subtext.
• The script never exploits the visual potential of joy—using a sunrise, a warm flame, or a physical gesture—to contrast with the film's darkness. The scene 2 promise of burgers is paid off in the last sequence, but the connection could be stronger if a burger was shown as a central image, almost a symbol of safety, throughout the film.

Suggestions

• In scene 2, extend the banter an extra two lines: Noah could say 'Burgers, fries, no phones,' and Mara replies 'And no complaining when the fries are cold because we got stuck in traffic.' That would make the audience feel a promise being kept when they actually order fries in the final scene.
• Consider adding a small beat in scene 5 where the group stands in the elevator and Mara, trying to lighten the mood, tells Noah she'll let him pick the radio station. A half-smile from Noah amidst the terror would make the later loss of safety more painful.
• In scene 27, after Noah rings the bell, have Mara put her hands on his shoulders and say 'You're grounded' with a tiny smile. It would transform the kiss into a complete emotional beat: protective, amused, and heartbreaking because they are still not safe.
• In scene 35, when Noah cries against his mother, give Mara a line that is pure parental humor: 'It’s okay to cry. I won’t tell the tunnel people.' That would allow a small laugh even in the midst of tears, making the joy more complex.
• Because the film is so grim, schedule a single moment of 'gross-out joy' in the tunnels: for example, the group sees a pocket of clean air and a broken vending machine, and they all cheer for a stale bag of chips. Such a beat would reinforce their humanity and make the despair of the CO2 scenes more devastating.

Questions for AI

• How can the existing banter between Mara and Noah be used to plant emotional payoff scenes without feeling like manufactured comedy?
• Is there a place in the middle act where a sudden, unexpected laugh could change the audience’s understanding of a character, such as Rourke revealing an absurdly common fear that contrasts with his arrogance?
• What small physical gesture—like a shared blanket or a fist bump—could be introduced early, lost during the crisis, and then restored in the final scene to create silent joy?
• Does the absence of joy in the second half make the film feel monotonous, and should the script include a brief music cue or visual motif (like the snowcat headlights) that comforts the audience?
• How can the joy of survival in the diner scene be balanced with explicit mourning, so that it doesn't feel like a betrayal of the characters who died?

Executive Summary

Sadness is the counterweight to the screenplay's thrills, giving the horror a human cost. The script pieces together a series of tragic sacrifices and emotional wounds—Bryce being used as a puppet, Theo's willing fall, Rourke's lonely atonement, and Walt's repeated confrontation with his dead wife—that make the audience feel every death as more than a plot point. The most powerful sadness is intertwined with love: a mother's guilt, a son's fear of losing her, a man's regret for not listening to his daughter, and a veteran's unresolved grief. The final diner scene, where Mara sets Walt's master key beside her silenced phone, translates an entire night of losses into a single, wordless image.

Usage Analysis

• Scene 2 introduces sadness through a single text message: 'I'M SORRY, BUD. ROADS ARE A MESS. NEXT WEEKEND?' Noah locks the screen before Mara can see it. In one gesture, the audience understands years of broken promises, and the sadness is carried in Noah's quiet acceptance.
• Scene 5's loss of Bryce is made sadder by Mara's 'I had him' and the smear of blood on her palm. The creature's mimicry of Bryce's voice calling 'Mara' as they retreat turns the natural grief of a sudden death into a lingering, taunting sorrow.
• Scene 23's trestle sequence contains the most poignant death in the script: Theo, deciding to unclip himself and fall with the creature, tells the others to 'Tell Nisha she still owes me a better bandage.' His sacrifice is presented as a quiet choice, and the detail of Noah pulling the still-warm key from the debris transforms a monster attack into a moment of pure loss.
• Scene 26's vent-chamber confrontation with Margaret's voice gives sadness a formal structure: Walt hears his dead wife say 'I miss you,' and he replies 'Me too' before returning to his task. The scene doesn't over-explain; it is a moment of private grief made public through the horror, and it raises the emotional stakes of his survival.
• Scene 36 uses a prop to hold the film's sadness: Walt's master key, placed beside Mara's dead phone on the diner table. That single, silent image implies the loss of a man who was part of the mountain's soul, and it allows the audience to mourn without a single line of dialogue.

Critique

• Sadness is deployed effectively but somewhat unevenly; it is heavily concentrated in scenes 23 and 26, while the earlier deaths (Bryce, and even the 1944 soldiers) are processed as plot mechanics more than as emotional events. The script might feel more cohesive if each death had a shared thematic echo, such as all characters losing people they failed to listen to.
• The script handles sadness with restraint, which is admirable, but it occasionally undercuts the power of grief by immediately returning to danger. For example, after Theo's death, the group moves almost instantly into the next conflict with Rourke. While realistic, this can prevent the audience from processing the loss; a beat of silence or a visual reminder (like the key) could help the grief land.
• Mara and Noah's relationship carries significant unspoken sadness—Noah’s father is absent, and Mara's 'scar tissue' hints at her own trauma—but these threads are not fully emotionally explored. The script plants them, but the sadness of their personal history could be deepened in the third act without slowing the pace.
• The character of Rourke becomes sympathetic only in scene 33 when he sacrifices himself. The sadness of his death is well-earned, but it could be stronger if the script had earlier given him a moment of vulnerability, such as a scene in the operations center where Mara sees him looking at an old photo of his daughter and quietly chooses not to judge him.
• The 1944 prologue introduces a rich vein of sadness—the soldiers trapped and sealed, the 'DO NOT ANSWER' warning scrawled by someone who was clearly traumatized—but the film does not revisit that historical grief until scene 10. Reinserting a visual or auditory echo of the 1944 men in the present-day tunnel could make the ancient tragedy feel synchronous with current events.

Suggestions

• After Theo's death in scene 23, add a two-second shot of the remaining brass key around Noah's wrist as he climbs, so the audience carries that sadness into every subsequent action scene.
• In scene 26, make Walt's final line, 'Pension plan,' followed by a laugh, a tie to a story he told earlier about his wife telling him to take the pension. That would transform his gallows humor into a direct reference to the life he is giving up, making the sadness more personal.
• In scene 33, when Rourke is taken, allow Mara to lose a fraction of her control: perhaps her voice breaks when she says 'Tell her I listened,' and she has to pause before continuing the plan. That crack is more impactful than a composed response.
• In the final diner scene, have Noah pick up Walt's key and hold it, then hand it to his mother without a word. That physical passing of grief would show that Noah is not just a protected child but a participant in mourning, deepening the sadness of the epilogue.
• Consider adding a brief flashback in scene 21 to the 1944 soldier who wrote the warning: a single shot of him chiseling those letters in the dark while hearing voices, then quickly cutting back to the present. This would connect the historical sadness to the contemporary characters without adding a new subplot.

Questions for AI

• How can the script use the sense of grief to make the audience care about the creature's loss as well, perhaps by showing that it is a wounded animal rather than a pure villain?
• Is Mara's emotional armor too impenetrable, and should there be a scene where she openly cries, or would that undermine her role as the story's anchor?
• What visual symbol could pop up multiple times across the film—like a missing wedding ring, a locket, or a child's drawing—so that the audience sees a character's sadness grow over time?
• Does the death of Theo receive enough screen time for its emotional weight, and could a short eulogy from Nisha or Devon give the audience a more concrete reason to mourn him?
• How can the sadness of the 1944 victims be integrated into the modern rescue attempt without feeling like a contrived history lesson?

Executive Summary

Surprise is used sharply but sparingly, which makes each twist land with impact. The script’s surprises are not just jump scares; they are reversals that redefine the audience's understanding of the creature, the characters, or the plan. The most successful surprises are the ones that force a new realization about the threat—like the live voice if playback, the body puppet, or the creature's ability to learn patterns. The screenplay also uses character reversals (Rourke’s sudden turn into bait, Theo’s unspoken sacrifice) to keep moral expectations unstable. However, some surprises rely on withheld information (Rourke's memo, the 1972 report) and could feel less organic to the audience if the clues are too thin.

Usage Analysis

• Scene 1’s surprise is existential: the voice of a man the audience was told is dead, then a child’s 'Daddy,' then Voss's own whisper. The escalation makes the listener's mind race to construct an explanation that the characters already know is impossible, creating an disorienting effect.
• Scene 4 delivers a pure genre surprise: the audio playback from the camera is 'live,' and the cable yanks back with terrifying force. The blood on the lens immediately follows, turning a moment of curiosity into a sudden blast of violence.
• Scene 11 contains the twist of Bryce’s apparent survival being a puppet. The audience is given a moment of hope—Bryce saying 'Mara' and the group's relief—before the body jerks and the pale forelimb appears. This is an emotional whiplash that the script uses to devastating effect.
• Scene 14 exposes Rourke’s lie about the anomaly and the 1972 memo. The surprise is less a jump scare than a moral bombshell, making the audience re-evaluate the entire chain of events and realise that the disaster was not just a natural accident but a deliberate cover-up.
• Scene 32’s avalanche climax contains two surprises: Rourke’s self-sacrificial choice to drive into the bowl, and the creature’s ability to survive the avalanche and grab Mara. The surprise is double, giving the audience a moment of hope in Rourke’s redemption and then a moment of horror in the monster's invincibility.

Critique

• Surprise is most effective when it grows out of established rules—the creature mimics voices, so the discovery that it can also mimic a live radio transmission is a natural escalation. The script uses this well in scene 33 when the creature picks up the radio and says 'Noah'.
• The character surprise of Rourke turning into a sacrificial hero in scene 32 is powerful because it contrasts with his earlier self-serving behavior. However, the transition is somewhat abrupt; a smaller act of altruism earlier, such as volunteering to cover the rear or sharing his intel, would make the final leap more believable.
• The 'Rourke hid the memo' surprise in scene 14 is effective on a logical level, but the audience may feel cheated because they never saw enough evidence earlier. Mr. Rourke’s dismissal of Hannah’s warning and his schedule-certainty argument are enough for a causal viewer, but a dedicated audience member might want a more visible clue, like a map in his office or a half-torn file folder.
• The script's biggest surprise—the depth of the military connection in scene 18—is more of a slow reveal than a sudden twist. It works, but the 'Subject B' designation is introduced and dropped quickly. That is a missed opportunity for a surprising, delayed payoff if it had been referenced earlier.
• The final surprise of the film is the creature surviving the collapse and appearing to take Rourke. This is a conventional horror twist, but because the audience is expecting the creature to survive the avalanche, the surprise is somewhat muted. The true shock is Rourke’s death, which lands better because it is not advertised.

Suggestions

• In scene 4, add a half-second shot of the tablet's audio waveform appearing to inhale before Bryce’s recorded line, then cut to the clean waveform of the real voice. The audience would see a visual surprise in the data itself, reinforcing the theme of imperfect mimicry.
• To make Rourke’s memo surprise feel more earned, insert a throwaway shot in scene 3 of Rourke’s phone showing an encrypted file named 'ORPHEUS' when he checks it, so the audience has a subconscious cue that he knows more than he says.
• In scene 11, after the creature is revealed and Bryce falls, the script could include a short beat where Noah, watching through the glass, whispers 'It used him'—so the audience sees the surprise through a child's eyes, making the horror more emotionally complex.
• In scene 32, when Rourke throws the flare at the creature and yells 'Stay with me,' give him one more line: 'For Claire.' That turns a physical surprise (the redirect) into an emotional revelation, deepening the twist of his sacrifice.
• The scene 33 creature survival could be made more surprising by adding an extra beat of triumph—the whole group on the ridge celebrating, hugging, and preparing to drive down—before the pale hand punches through the snow. The audience should be lulled into a false ending.

Questions for AI

• How can the script distinguish between earned surprises (from character decisions) and mechanical surprises (from plot devices) so that the audience never feels tricked?
• What is the emotional benefit of keeping the creature’s true form hidden until scene 26, and would a partial reveal in scene 16 improve the surprise of the full-body reveal?
• Is there a way to make the 'Subject B' reveal more surprising by having the audience assume the creature is unique, and then discovering there might have been an 'A' full of smaller offspring?
• How can Rourke’s self-sacrifice feel less like a redemptive arc and more like a surprising but motivated choice, given his earlier refusal to be bait?
• Which surprise beats in the story should be kept in the trailer versus hidden to preserve the audience's experience?

Executive Summary

Empathy is the screenplay's emotional glue, making the audience care about a large ensemble of characters in a crisis. The script earns empathy by giving each character a humanizing detail—Noah’s hidden loyalty, Mara’s chronic guilt, Walt's grief, Theo's selfless humor, Rourke's estranged daughter—and then putting those characters through trials that test those same details. The audience is not just afraid for the group; it is afraid for specific people, and that makes the fear and sadness resonate. The creature’s mimicry is a diabolical empathy weapon: it uses the characters’ love for each other to lure them into danger, which forces the audience to empathize with the characters on an even deeper level because we share their vulnerability.

Usage Analysis

• Scene 2 builds empathy through a single gesture: Noah lies about his dad making it to Boulder, and Mara pretends to believe him. The audience feels both of them protecting each other, and from that instant we are invested in their safety.
• Scene 9 establishes Mara’s leadership empathy through her line 'I had him' and her order 'Nobody goes anywhere alone.' Her guilt is for a colleague she couldn't save, and her protectiveness becomes the group’s central moral compass. The audience feels that her competence is fragile, which makes her relatable.
• Scene 17 shows Hannah’s competence as a geologist and then immediately places her in trauma as she applies a tourniquet to Theo. The audience empathizes with the strain of being the one who must keep calm while others are shredded—a different kind of heroism than Mara’s.
• Scene 23 gives Theo empathy through his last request about Nisha's bandage. Even in mortal terror, he cares about how someone else will feel, and the audience is devastated because they understand him enough to know he is not angry, only loving.
• Scene 35’s reunion is satisfying precisely because the audience has been asked to empathize with Mara and Noah's fear of losing each other. The physical embrace, with Mara wincing in pain but holding on, creates a somatic empathy—we feel what both of them feel, strain and relief together.

Critique

• Empathy is balanced unevenly across the ensemble: Mara, Noah, Walt, and Theo receive deep interiority, while Hannah and Devon remain functional but a little flat. The script would benefit from giving Hannah a personal tie to the tunnel (perhaps a parent who worked in the same type of construction) and Devon a secret guilt about an earlier rescue gone wrong.
• The creature, despite being a monster, is given enough physical description (blind, hairless, malformed) to evoke a flicker of pity in scenes like the 1944 film. The script at times rejects this pity—Mara saying 'Don't give it anything else'—which is an interesting tension, but the audience's empathy for the creature could be more explicitly explored, adding nuance.
• Rourke’s empathy arc is clear—he goes from a self-serving contractor to a man dying to reconnect with his daughter—but the transition happens at the very end. The audience may not have enough shared time with him to feel the full weight of his sacrifice, since his redemption arc is compressed.
• The script's focus on empathy for the group sometimes comes at the expense of empathy for the broader community of trapped motorists. Scenes like 6 and 13 show their panic, but we rarely learn anyone's name. The mother with the asthmatic child is a good start, but a personal detail for the skier or the woman who asked about the tunnel would make the CO2 threat feel more tragic.
• Empathy between characters is well used to create conflict: Mara’s protectiveness toward Noah is pitted against Noah’s desire to be useful, and both sides are understandable. That dual empathy is rare and valuable. The script should seek more moments like this, where two characters’ valid fears push against each other.

Suggestions

• In scene 9, add a moment where Nisha, treating Pete, notices the key lanyard on Theo's wrist and asks about it. Theo says 'It was my brother's. He drove this pass.' This small personal detail would make Theo's later sacrifice even more empathetic because we know the truck was family.
• In scene 17, when Hannah applies the tourniquet, allow her to whisper a statistic to herself: 'Survival rate is 97% if you get a tourniquet in two minutes.' This shows she is using her scientific brain to stay calm, and the audience empathizes with her need for control.
• Give Devon a habit of checking a wedding ring or a photo in his vest during quiet moments. In scene 23, when Theo falls, let Devon remove the ring and put it in his pocket, telling no one, so the audience understands he is carrying home a part of Theo.
• In the final diner scene, after Mara silences the phone, have Noah take her hand and say, 'Dad can wait.' That small family empathy gesture would align with the theme that they have chosen each other, and would give the audience a final emotional reward.
• To make the audience empathize with the trapped motorists, open scene 13 with the skier and the pregnant wife having a private exchange where he gives her his jacket. That would turn background players into interconnected humans, so the later silence from the tunnel matters more.
