“How is there a shark in a freshwater cave system?” Ahaha good question! Maybe it got in during a flood? Prime Video has revealed the official trailer for a shark movie horror thriller titled The Devil’s Mouth, set in Thailand in scary cave. This was actually filmed on location in Thailand over 8 weeks with an impressive cast of well-known youngsters. Made by genre filmmaker Jeff Wadlow (of Cry Wolf, Never Back Down, Kick-Ass 2, Truth or Dare, Fantasy Island, Imaginary) it’s another shark movie this year – but with some extra horrifying, extra munchy sharks in these waters. A group of college friends’ Thailand adventure turns deadly when they become trapped in submerged caves with a perilous predator. As oxygen runs low, past conflicts emerge in the desperate fight for survival. There is some kind of “devil’s mouth” creature prowling the water. Starring Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong. This actually looks ridiculous enough to play well in theaters! But of course it’s being sent direct to streaming on Prime Video as a summer horror offering instead. Enjoy the fun trailer.
Here’s the official trailer (+ poster) for Jeff Wadlow’s movie The Devil’s Mouth, direct from YouTube:
“Getaway just got a whole new meaning.” Five adolescent friends decide to explore The Devil’s Mouth cave system in Thailand for one last adventure before life in the real world begins. But they soon discover that something is hunting them under the water… rapid, noiseless, and deadly. In the suffocating darkness, trust erodes, panic spreads and every wrong turn becomes a fight for survival. The Devil’s Mouth is directed by American genre filmmaker Jeff Wadlow, director of the films Cry Wolf, Never Back Down, Kick-Ass 2, True Memoirs of an International Assassin, Truth or Dare, Fantasy Island, The Curse of Bridge Hollow, and Imaginary previously, plus the “Are You Afraid of the Dark?” horror series. The screenplay is written by Aja Gabel & Myung Joh Wesner, along with Jeff Wadlow. Produced by Basil Iwanyk, Erica Lee, Jeff Wadlow. Made by Lionsgate & Thunder Road Films. Amazon MGM Studios debuts Wadlow’s The Devil’s Mouth shark movie streaming on Prime Video starting July 29th, 2026 coming up this summer. Who wants to watch?
