Five friends set out on one last adventure along Thailand's stunning coast, eager for a final thrill before life in the real world begins. They sign up for a guided swim through a remote cave system known as The Devil's Mouth, a natural wonder that's as breathtaking as it is unforgiving. Deep inside the labyrinth of narrow waterways, their journey takes a terrifying turn when they discover that a freak storm the week before flooded the caves with sea life. The creatures died in the fresh water, but something survived... and it's hunting them now--fast, silent, and deadly. Every corridor they round is overflowing with anxiety, and every wrong turn becomes a deadly encounter. As panic spreads and their sense of direction slips away, the group begins to fracture. Trust erodes, fear takes over, and survival becomes a savage game. In the suffocating darkness, every choice could be their last as they learn that to make it out alive, sacrifices must be made.

Peter Travers The Travers Take Jul 31, 2026
1.5/4
It’s been hyped as the first fresh-water shark movie. Sad to say, that’s the only thing fresh about it. Go to Full Review

It’s just aggressively forgettable instead of memorably awful, which is almost worse. Go to Full Review
Guy Lodge Variety Jul 30, 2026
It’s the shark’s appearances, surprisingly, that lack bite. Denied a point of view or much in the way of a closeup, the CG killer never feels a particularly distinctive or palpable presence, while its lunges take on a fairly predictable pattern. Go to Full Review
Chelsea Hui Mamamia Sep 8, 2026
It's moody, deeply atmospheric and packed with enough claustrophobic tension to keep you on the edge of your seat or, if you're anything like me, completely cowering behind your hands in the dark. Go to Full Review

I'm not sure how you make a 'The Descent'-but-with-a-shark movie boring, but 'The Devil's Mouth' proves that anything is possible. Go to Full Review

Jim S @RT55723453 4 days ago This movie has gotten terrible reviews, and honestly I don't understand why. It's a perfectly fine horror thriller for what it is. It's not trying for the lofty goals of The Descent, nor is it seeking to be the next Jaws. It IS trying to create a tense thriller that mashes the danger of cave diving with creature feature terror, coming at a cast of young entitled people who are about as stupid as they get. Terrible things happen, mostly that they bring on themselves, and we get to enjoy the ride. The effects were pretty cool, the acting was solid for the types of characters we were getting. Honestly, I don't get the bashing. Didn't care for it? Fair enough. But to call it terrible means perhaps you didn't get what the film was going for. Want a horror thriller that you shouldn't take too seriously, with quality effects, some good jumps, and a satisfying finish? This could do! See more Jose N @soyjosenieves Oct 3, 2026 Una película para pasar el rato. Tiene algunos momentos de tensión, pero el guion no termina de funcionar. See more nati N @RT34039372 Oct 3, 2026 First of all, don't watch this movie. Second, all the actors are just terrible, including the lead actress. It almost seems like these are people with no ability to express emotions. Someone died? "Oh, my friend died. Let's move on." In addition, the CGI is awful—at the level of movies from 2002. And the cheesiness—the cheesy lines they say are just so bad that you simply can't stand this movie. See more Brian G @Goodwibr Sep 30, 2026 Unlikeable characters making bad decisions while trapped in underwater caves, being stalked/eaten by a shark. You spend the movie with these insufferable characters, progressing through increasingly preposterous scenes, until the movie is full-on insulting your intelligence as a viewer. The shark special effects were pretty good, and there is some quality in the filmmaking. Also, the main character, played by Katheryn Newton was the one character that wasn't completely awful, and she was an acceptable protagonist. But MAN was this a tough one to get through. See more J L @RT50306127 Sep 30, 2026 One of the worst movie I ever seen. RT See more Marco L @decatur555 Sep 27, 2026 The cave setting gives The Devil's Mouth an effective survival premise: confined spaces, darkness, water and a predator are enough to create some genuine tension. Kathryn Newton and Lana Condor help carry the film, and the claustrophobic setting works best when the threat remains physical and immediate. The problem is how quickly everything becomes familiar. Too many situations are easy to predict, several solutions can be guessed well in advance, and the logic behind the shark's presence in such an isolated environment becomes increasingly difficult to ignore. Jeff Wadlow keeps things moving and delivers a few effective B-movie moments, so it is never a complete failure. But originality is scarce, and most of its ideas feel borrowed from stronger survival and shark films. Watchable, occasionally tense, but far too formulaic to leave much of an impression.
