Wadlow added, “I think the other reason why it will never stop is when you take that very real, very dangerous situation, and you push characters through that pressure cooker, it reveals them. And that will always work. You’ll always be looking for ways to take your characters and get them to reveal who they are, to force them to change. The storytellers, that’s the holy grail for us. And it’s so easy with a shark.”
He’s onto something there, my friends. Fans like myself return again and again to the sharksploitation genre because that primal fear rests so deeply in our bones (even if we know sharks are not the monsters we sometimes view them as). And part of the strength of The Devil’s Mouth is that it is a story about people first.
Outside of being a fan of the subgenre and having “always wanted to make a shark movie,” it’s the relationship between the characters that caught Jeff’s eye. “I read the script, and it’s really a wonderful script written by Aja Gable and Myung Joh Wesner, two very talented young female writers. It’s a very authentic study in female friendship. This isn’t just a body count movie where you’re waiting for these horrible characters to die. I mean, you kind of love all the characters and that was on the page, and I got excited about it for that reason.”
Personally, my favorite element of The Devil’s Mouth is the relationship between Newton and Condor’s characters. Newton plays a woman who is always doing what her friend wants and is never allowed to take the lead, even when she knows she’s right. That’s something many of us can probably relate to.

Of course, it’s one thing to read a great script, and another to shoot the thing. That’s especially a challenge with aquatic horror films, which are notoriously difficult to make. “It’s the hardest thing I’ve ever done, and I’ve run a bunch of marathons,” admits Wadlow. “But I love a challenge, and it’s one of the reasons why I love filmmaking. There’s a moment in this movie where we were doing the underwater stuff. I would get in the water every day. I would block with the actors and the camera operators in the water. But when we were doing the actual underwater tunnel sequence, I couldn’t get in the water. It would be too dangerous. So, I would draw the set on this whiteboard. It was so hard to figure out, and there were moments where I did start to despair a little bit. I would turn around, I would see all these people, dozens and dozens of people, just there to support what we were doing and be on the team, and it was such an incredible feeling. It made my chest swell. So it was challenging, but I was very fortunate that I had a fantastic team.”
Difficult as shooting the film must’ve been, there are worse things than making a movie at such stunning locations as what’s featured in the film. The Devil’s Mouth incorporates gorgeous places all around Thailand, as well as an impressive cave set where the majority of the film was shot, one that displays the title Devil’s Mouth, a gnarly opening that looks like the jaws of a shark.
“One of my ideas for this film was I wanted to start as big as possible and then get as small as possible so we could really create that feeling of claustrophobia,” recalls Wadlow. “You start big, you get small, and people really feel the smallness. So we shot at real locations all over Thailand. I wanted to feature the beauty of Thailand. And then we went to real caves. We shot all these caves down in the southern part of Thailand, in Krabi, where they have these amazing freshwater cave systems where rescue divers actually train. And so when they’re getting in the water, and they’re swimming in and around the first couple caves, those are real. But then we get into the meat of the movie, where we’re obviously on a stage. We had these awesome sets that we built on sound stages in Bangkok and flooded with water.”
So, despite the difficulty of the shoot, would he do it all again? “There’s a sick little part of me that wishes they would lose the footage,” jokes Wadlow. “I could just start over, right? I’m like, I know how to do this now. I figured it out. Let’s do it again. So yes, I would do it again, but I’m looking for the next challenge.”
The Devil’s Mouth is a story that’s all about rising to the challenge and facing the next one. Whatever Wadlow takes on next, rest assured, he’ll arrive prepared and ready to face it.
And you can soon face the terrors of the deep when The Devil’s Mouth streams on Prime Video on July 29th.
