While part of the cast of The Devil’s Mouth was at Obsessed Fest to meet with fans, Prime Video has just unveiled the trailer for its horror thriller directed by Jeff Wadlow (Nightmare Island, Truth or Dare).
Set to premiere on the streaming platform on July 29, 2026, The Devil’s Mouth follows a group of friends who decide to enjoy one last trip to the Thai coast before getting back to their daily lives and entering adulthood. But when they venture into a spectacular network of underwater caves, their getaway turns into a nightmare. Trapped underground, they become the target of a creature as fast as it is silent… and particularly deadly, as this first trailer hints.
The cast brings together several familiar faces for TV and movie fans, including Kathryn Newton (Big Little Lies, The Society), Lana Condor (Deadly Class, the To All the Boys trilogy), Nico Hiraga (The Power, Love in Taipei), Gavin Casalegno (The Summer I Turned Pretty, Walker), and Tommi Rose (Sweet Magnolias, I Am Franky) in the lead roles.
