The Devil’s Mouth Trailer and Poster From Prime Video
Prime Video has released the official trailer and poster for The Devil’s Mouth, the upcoming survival horror film directed by Jeff Wadlow (Imaginary, Fantasy Island, Truth or Dare, and Kick-Ass 2).
Blending suspense, underwater thrills, and emotional character dynamics, The Devil’s Mouth delivers an immersive survival experience and a fun summer adventure.

Featuring a rising young adult ensemble cast including Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, and Tommi Rose, the film captures the humor and energy of college grads before plunging audiences into a fight for survival.
Set against the stunning backdrop of Thailand’s coastal caves, the film transforms a natural wonder into a claustrophobic nightmare, with danger lurking around every corner.

In The Devil’s Mouth, five friends set out on one last adventure along Thailand’s stunning coast, eager for a final thrill before life in the real world begins. They sign up for a guided swim through a remote cave system known as The Devil’s Mouth, a natural wonder that’s as breathtaking as it is unforgiving.
Deep inside the labyrinth of narrow waterways, their journey takes a terrifying turn when they discover that a freak storm the week before flooded the caves with sea life. The creatures died in the fresh water, but something survived… and it’s hunting them now— fast, silent, and deadly.

Every corridor they round is overflowing with anxiety, and every wrong turn becomes a deadly encounter. As panic spreads and their sense of direction slips away, the group begins to fracture.
Trust erodes, fear takes over, and survival becomes a savage game. In the suffocating darkness, every choice could be their last as they learn that to make it out alive, sacrifices must be made.

The cast includes Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong. The screenplay is by Aja Gabel and Myung Joh Wesner.
Produced by Basil Iwanyk, p.g.a., Erica Lee, p.g.a., and Jeff Wadlow, p.g.a., the film is executive-produced by Carsten H. W. Lorenz, Will Flynn, and Sam Greenberg. The Devil’s Mouth is rated PG-13 for violent content, bloody images, some language, and suggestive material.
