After re-teaming with Radio Silence and surviving the latest game with Samara Weaving in Ready or Not 2, modern scream queen Kathryn Newton is about to head to Thailand for her next bone-chilling feature. She’ll trade running from killer families on the grounds of the Danforth complex for delving into The Devil’s Mouth, a remote cave system that’s just as wondrous as it is terrifying. Premiering later this month on Prime Video, the film casts her as one of five friends embarking on a magical final summer adventure that soon becomes anything but. Ahead of its arrival, Collider can exclusively share a new poster highlighting the survivors and the threat wading into the titular cave’s flooded twists and turns alongside them.
The promo piece centers on the Devil’s Mouth itself, which shows exactly why it got its name with an entrance that looks like a set of jaws opening up to devour any foolish enough to enter. Those hapless victims include Newton, who’s front and center alongside To All the Boys franchise star Lana Condor, followed by their friends, played by Nico Hiraga, Gavin Casalegno, and Tommi Rose, and their guide for the expedition, Tayme Thapthimthong. Despite wearing headlamps, however, they seem completely unaware of the danger lurking just ahead of them. The Devil’s Mouth is a classic shark survival thriller, but instead of being out in the open water, the group is trapped in the narrow, winding confines of the cave with the apex predator and nobody coming to save them.
A week before the friends began their guided swim into the caves of Thailand, a major storm caused massive flooding that sent all manner of sea creatures into the fresh waters of the cave, where they soon died. It gives the Devil’s Mouth an eerie vibe as they venture in and makes it all the more terrifying when they find a shark somehow surviving what should be an inhospitable environment. Silent, deadly, and hungry, it’s ready for them at every wrong turn or slip that sends them plummeting into its domain. The film follows along as the group starts to get disoriented within the dark corridors and begins tearing itself apart as reason gives way to basic survival instincts and sacrifice becomes their only hope of escape.
Collider Exclusive · Horror Survival Quiz Which Horror Villain Do You Have the Best Chance of Surviving? Jason Voorhees · Michael Myers · Freddy Krueger · Pennywise · Chucky
Five killers. Five completely different ways to die — if you’re not smart enough, fast enough, or self-aware enough to avoid it. Only one of them is the villain your particular set of instincts gives you a fighting chance against. Eight questions will figure out which one.
🏕️Jason
🔪Michael
💤Freddy
🎈Pennywise
🪆Chucky
01
Something feels wrong. You can’t explain it — you just know. What do you do? First instincts are the difference between the survivor and the first act casualty.
02
Where are you most likely to find yourself when things go wrong? Setting is everything in horror. Where you are determines which rules apply.
03
What is your most reliable survival asset? Every survivor has a quality the villain didn’t account for. What’s yours?
04
What kind of fear is hardest for you to fight through? Knowing your weakness is the first step to not dying because of it.
05
You’re with a group when things start going wrong. What’s your role? Horror movies are brutally clear about who survives group situations and who doesn’t.
06
What’s the horror movie mistake you’re most likely to make? Honest self-assessment is a survival skill. Denial is not.
07
What’s your best weapon against something that can’t be stopped by conventional means? Every horror villain has a weakness. The survivors are always the ones who find it.
08
It’s the final scene. You’re the last one standing. How did you make it? The final survivor always has a reason. What’s yours?
Your Survival Odds Have Been Calculated Your Best Chance Is Against…
Your instincts, your strengths, and your particular way of thinking under pressure point to one villain you actually have a fighting chance against. Everyone else — good luck.
Camp Crystal Lake · Friday the 13th
Jason Voorhees
Jason is relentless, but he is also predictable — and that is the gap you would exploit.
He moves in straight lines toward his target. He doesn’t strategise, doesn’t adapt, doesn’t outsmart. He simply pursues.
Your ability to keep moving, use the environment, and resist the panic that freezes most victims gives you a genuine edge.
The Crystal Lake survivors were always the ones who stopped running in circles and started thinking about terrain, water, and distance.
You think like that. Which means Jason, for all his indestructibility, would face someone who simply refused to be where he expected.
Haddonfield, Illinois · Halloween
Michael Myers
Michael watches before he moves. He is patient, methodical, and almost impossible to detect — until it’s too late for anyone who isn’t paying close enough attention.
But you are paying attention. You notice the shape in the window, the car parked slightly wrong, the silence where there should be sound.
Michael’s power lies in the invisibility of ordinary suburbia — the fact that nothing ever looks wrong until it already is.
Your spatial awareness and instinct to map every room, every exit, and every shadow before you need them is precisely the quality Laurie Strode had.
You are not a victim waiting to happen. You are someone who already suspects something is wrong — and acts on it.
Elm Street · A Nightmare on Elm Street
Freddy Krueger
Freddy wins by getting inside your head — using your own fears, your own memories, your own subconscious as weapons against you. That strategy requires a target who can be destabilised.
You are harder to destabilise than most. You’ve faced uncomfortable truths about yourself and you haven’t looked away.
The survivors on Elm Street were always the ones who understood what was happening and chose to face it rather than flee from it.
Freddy’s greatest weakness is that his power evaporates in the presence of someone who refuses to give him the fear he feeds on.
Your psychological resilience — the ability to stay grounded when reality itself becomes unreliable — is exactly the quality that keeps you alive here.
Derry, Maine · It
Pennywise
Pennywise is ancient, shapeshifting, and feeds on terror — but it has one critical vulnerability: it cannot function against someone who genuinely stops being afraid of it.
The Losers Club didn’t survive because they were braver than everyone else. They survived because they faced their fears together, and faced them honestly.
You ask the questions others avoid. You look directly at what frightens you rather than turning away.
That directness — the refusal to let fear fester in the dark — is Pennywise’s worst nightmare.
It chose the wrong target when it chose you. You are exactly the kind of person whose fear tastes like nothing at all.
Chicago · Child’s Play
Chucky
Chucky’s greatest advantage is that nobody takes him seriously until it’s already too late. He exploits the gap between how something looks and what it actually is.
You don’t have that gap. You take threats seriously regardless of how they present — and you never make the mistake of underestimating something because of its size or appearance.
Chucky relies on surprise, on the delay between recognition and response. You close that delay faster than almost anyone.
Your instinct to treat every unfamiliar thing with appropriate scepticism — rather than dismissing it because it seems absurd — is the exact quality that keeps you breathing.
Against Chucky, not laughing is already winning. You are very good at not laughing.
Who Is Behind ‘The Devil’s Mouth’?

The Devil’s Mouth snapped up an experienced horror maestro in Jeff Wadlow to direct from a script by Little Fish‘s Aja Gabel and Star Wars: Skeleton Crew writer Myung Joh Wesner. Wadlow most recently helmed the Blumhouse flick Imaginary, but he’s perhaps best known for his work on 2018’s Truth or Dare and the superhero comedy sequel Kick-Ass 2. Joining him as producers are two veteran John Wick producers, Basil Iwanyk and Erica Lee, who are attached through their Thunder Road Films banner. As the cherry on top, Emmy-winning composer Bear McCreary, known for everything from series like Outlander to video game giants like God of War, composed the score.
The Devil’s Mouth premieres on Prime Video on July 29. Check out the new poster above.
