If you loved Bloody Hell, try Sanctum
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Alister Grierson, and they sit in Action / Thriller territory. If that's the register that drew you to Bloody Hell, the second film will land in a comparable space — through a different lens.
What Sanctum is
Esa-ala Caves, monsoon season, scuba gear scattered. A flash flood traps Frank McGuire's team, including his son Josh, in an underwater maze. This tense thriller is best watched on a small screen to amplify its claustrophobic effect.
