Overview
- The Devil’s Mouth premiered on Prime Video on July 29, 2026 as a streaming original timed to coincide with Shark Week and immediate reviews began circulating that day.
- The plot sends five recent college graduates into a flooded freshwater cave in Thailand where a bull shark — a species that can live in both salt and fresh water — stalks them.
- The screenplay began on the 2019 Black List and the production shot scenic opening sequences on location in Thailand before filming most cave scenes on soundstages using practical sets.
- Critics give the film a mixed reception: Kathryn Newton’s performance is widely praised as the emotional anchor, while reviews call out thin character writing, repetitive plotting, uneven CGI and effects, and a PG-13 rating that limits on-screen violence.
- The film fits a 2026 trend of shark-centered releases and streaming-first mid-tier genre movies, a pattern that boosts visibility through timing and star casting but may limit box-office exposure and expectations for gore-driven creature features.
