As Prime Video’s summer of obsession continues, a movie that breaks the typical mold of romance or a book adaptation is The Devil’s Mouth, a survival thriller. The trailer has arrived, and the latest summer shark movie will start streaming on Prime Video July 29.
The film stars Lana Condor, Kathryn Newton, Gavin Casalegno, Nico Hiraga, Tommi Rose and Tayme Thapthimthong.
A co-production with Lionsgate, it follows a group of college friends on a trip to Thailand. Underwater camera angles follow them as they jump off a boat into crystal blue waters, but nothing happens there. It’s the cave system known as The Devil’s Mouth where the real danger lurks.
Thapthimthong (The White Lotus) serves as the group’s guide through the caves that give the film its title. Condor is known for portraying Lara Jean Song Covey in Netflix’s To All The Boys I’ve Loved Before films. Newton just appeared in Ready Or Not 2: Here I Come and plays Cassie Lang in Ant-Man: Quantumania (2023). Casalegno portrays Jeremiah Fisher in The Summer I Turned Pretty. Tommi Rose can be seen in Outer Banks. Hiraga is known for starring in Sweethearts from New Line on HBO Max as well as Olivia Wild’s Booksmart and Paramount+’s Love in Taipei.
The opening to the freshwater grotto looks a lot like the mouth of a shark with jagged rocks that resemble pointy teeth. When Newton’s character starts spotting dead animal bodies floating around in the water and then a cloud of blood deeper down, she realizes something’s wrong. Thapthimthong’s guide pulls a shark tooth from a pair of cracked goggles that float to the surface, and then a bull shark attacks Gavin Casalegno’s character.
“How is there a shark in a freshwater cave system?” Condor’s character rightfully asks.

Aja Gabel (Sunny, The Staircase, upcoming Five Star Weekend) and Myung Joh Wesner (Star Wars: Skeleton Crew, High Potential) wrote the script, which was featured on the 2019 Black List alongside Leah McKendrick’s Voicemails for Isabelle, with latest revisions by director Jeff Wadlow.
Wadlow produces alongside Thunder Road Films’ Basil Iwanyk and Erica Lee, and Wadlow. Carsten Lorenz and Will Flynn are EPs. Scott O’Brien and Pavan Kalidindi are overseeing the project for Lionsgate.
At Prime Video’s Obsessed Fest fan event over the weekend, Casalegno told Deadline that “it’s on [his] bucketlis to do a shark movie.” Tune in July 29 to see which character dies, because he and costar Rose teased that, in this film, viewers won’t want any of the characters to die.
