Underwater

Most movies like to buy you a drink first. They give you twenty minutes of "character building" where you learn that the protagonist has a strained relationship with their father or a cat waiting at home. Underwater doesn’t have time for your cat. Within the first five minutes, the Kepler 822 station—sitting at the bottom of the Mariana Trench—is being crushed into scrap metal by a massive earthquake. I watched this while my radiator was clanking like a ghost in the pipes, and honestly, the mechanical groaning of my apartment added a 4D layer of dread that I didn’t actually pay for.

By the time the title card hits, Kristen Stewart (as Norah) is already sprinting through hallways filled with exploding pipes and rushing seawater. There is no "before the incident." There is only the frantic, wet, terrifying "now." This is contemporary sci-fi horror at its most efficient, stripping away the bloat of the franchise era to deliver a ninety-minute panic attack that feels like a spiritual successor to Alien (1979) and The Abyss (1989), but with the lighting turned down to "pitch black."

Grime, Grease, and Heavy Metal

Director William Eubank (who did the equally stylish The Signal) clearly understands that in the deep ocean, the environment is the first monster you have to fight. The production design here is spectacular. These aren't the sleek, Apple-store-inspired spaceships we see in modern blockovers; this is a rugged, industrial nightmare. The crew has to climb into "Big Daddy" style deep-sea suits that look like they weigh a ton—because, in reality, they nearly did. Kristen Stewart and the rest of the cast, including Vincent Cassel and Jessica Henwick, were lugging around suits that weighed upwards of 100 pounds.

You can see the genuine physical exhaustion on their faces. Underwater is what happens when a B-movie script accidentally walks into an A-list budget and refuses to apologize for it. The cinematography by Bojan Bazelli (A Cure for Wellness) manages to make the murky, sediment-filled water feel oppressive rather than just frustrating to look at. I found myself holding my breath during the sequences where they have to walk across the ocean floor, the beams of their flashlights barely cutting through the snow-like "marine snow" of the abyss. It’s an exercise in sustained tension that rarely lets up for a breath of air.

The Lovecraftian Pivot

For a while, Underwater feels like a standard "escape the collapsing building" thriller, just relocated to the bottom of the sea. But as Mamoudou Athie and John Gallagher Jr. start encountering... things in the dark, the film shifts gears. It moves from disaster flick into full-blown cosmic horror. Without spoiling the final act for those who missed its brief theatrical run, let’s just say it goes to a place that will make fans of H.P. Lovecraft very, very happy.

It’s rare to see a studio film commit this hard to a specific, non-franchise horror niche. Released right as the Fox-Disney merger was finalizing, this film felt like a "lost" artifact—a project that was filmed in 2017, sat on a shelf for three years, and was dumped into theaters in January 2020 just before the world shut down. Because of that, it’s gained a massive cult following on streaming. It doesn’t try to set up a "Deep Sea Cinematic Universe." It just tries to scare the hell out of you for an hour and a half and then rolls the credits.

Stuff You Didn't Notice

The trivia behind this one is almost as grueling as the plot. Kristen Stewart actually shaved her head for the role, not just for the look, but because she knew she’d be sweating in those helmets for twelve hours a day and didn't want to deal with hair touch-ups. Talk about commitment to the grime. Also, if you look closely at the monitors and blueprints throughout the station, the level of detail is insane—there are actual topographical maps of the Mariana Trench used in the background.

Perhaps the coolest bit of behind-the-scenes info is about the "big guy" at the end. While the script was vague, William Eubank has since confirmed in interviews that the creature is, indeed, Cthulhu. He even worked with the creature designers to ensure the scale was appropriately god-like. T.J. Miller's character carries around a stuffed bunny throughout the movie, which was an improv choice that the director kept because it added a weird, human touch to the metallic coldness of the suits. It’s those odd, "why is that there?" moments that make a cult classic stick in your brain.

Underwater is a lean, mean, and surprisingly beautiful piece of genre filmmaking. It’s the kind of movie I love discovering on a rainy Tuesday night—something that knows exactly what it is and executes it with zero fat. While it might lean a little too heavily on its influences at times, the sheer physical craft and Kristen Stewart's grounded, gritty performance keep it from feeling like a derivative knock-off. If you’ve ever looked at the ocean and felt a twinge of existential dread about what’s lurking in the dark, this movie is going to validate every single one of your fears.
