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

1.5/4
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

Stupid, annoying and hard to see might be the holy trinity of crap. 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

Brian G @Goodwibr 1 day ago 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 1 day ago One of the worst movie I ever seen. RT See more Marco L @decatur555 4 days ago 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. See more Boxmol 6 @RT89262859 Sep 24, 2026 Mindset of a movie from 2012 this isn't even horror anymore it's the typical vacation disaster shark and one character in the movie doesn't die movie, except this is in a cave this has been done too many times the problem is that the budget is 3.5m WTF? Don't ever make a movie again 😭 See more Andrei D @RT74856639 Sep 23, 2026 Decent creature feature that doesn't fully follow genre tropes; the shark sometimes behaves absurdly, there's a little too much deus ex machina See more alurq T @RT16621823 Sep 11, 2026 Utterly and abysmally stupid from start to finish. The damned cgi shark changes sizes throughout, apparently has Moby Dick ramming powers that rival Juggernaut and can eat 7 people in less than an hour. Let alone that Bull sharks are rare in Thailand, stay in deep currents, and would never be washed into a shallow riverine cave without a sea outlet regardless of any stupid storm surge. Somehow a seabird just dies from swimming in fresh water? Red tides affect an inland river cave and saltwater bioluminescent plankton just casually thrive in the same freshwater cave? How does anyone write such a stupid story and actually get it funded? This is why we can't have nice things! See more Read all reviews
