Underwater, no one can hear you scream. Well, they can if they’re nearby and can catch an earful of your terrified gurgling, but also, I wouldn’t recommend screaming, because you’ll need that oxygen, because you’re about to walk across the deep sea floor and try not to get eaten by a mysterious monster.
OK, so it’s not as catchy a tagline — but the isolated, hermetically-sealed sci-fi horror vibe of Underwater is too close to Alien not to have a go. (Alien But It’s) Underwater stars Kristen Stewart, Vincent Cassel, and Jessica Henwick (Game Of Thrones, The Force Awakens) as a ragtag bunch of adventurers in a scientifically advanced
space stationocean base.
