The Scene Drift

Prime Video has unveiled the official trailer and teaser poster for its upcoming survival thriller, The Devil’s Mouth, which is scheduled for global release on July 29, 2026. The film recently generated buzz when members of its cast appeared at Obsessed Fest in Los Angeles to promote the project.

Directed by Jeff Wadlow, the film follows a group of five college graduates embarking on a final pre-adulthood adventure along the coast of Thailand. The trip takes a dark turn when they sign up for a guided swim through a remote cave system known as "The Devil’s Mouth."

Following a severe storm that flooded the caves with sea life, the friends discover that a dangerous predator has survived in the labyrinthine waterways. The ensuing struggle for survival forces the group to navigate claustrophobic conditions and rapidly eroding trust.

The ensemble cast features Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong. The screenplay was written by Aja Gabel and Myung Joh Wesner. Producing the film are Basil Iwanyk, Erica Lee, and Jeff Wadlow, with executive producers Carsten H. W. Lorenz, Will Flynn, and Sam Greenberg.

With a runtime of 105 minutes and a PG-13 rating, The Devil’s Mouth blends elements of suspense and horror. 

The film will be available to stream worldwide on Prime Video beginning July 29.
