13. Frozen (2010)

“It does for skiing what Jaws did for swimming” announces the trailer for Frozen, a low budget thriller set on a set of treacherous slopes. Stuck on a broken down ski elevator for over a week, three friends must figure a way down to safety before they either freeze to death, starve to death, or both. With chancing the sheer drop seemingly the best option, the movie remembers to add hungry wolves down below, and it’s a case of choosing the lesser evil before they meet their maker anyway. Frozen is a bit of a forgotten gem, and ends up being quite grisly, as well as truly terrifying.

12. Identity (2003)

You’ll have come to realise from reading this list, if not before, that motels are a great breeding ground for fear, tension and claustrophobic horror. Identity might just be the best example of motel-based horror in recent memory, following a seemingly disparate group of people driven to the hotel by a freak rain storm. As they start to bite the dust one by one, we come to realise that they might not be as disconnected as they first thought. It’s one of those thrillers that revels in its twist ending for a little too long, but whether you’re on board with it or not, it never diminishes the fun.

11. Exam (2009)

Part of the relatively new corporate horror subgenre, British movie Exam smartly plays on our fear of job interviews and formal business settings. Appealing to people who watch The Apprentice and its various off-shoots, the movie brings together a group of eager job applicants and puts them in a room together. Asked to answer a cryptic puzzle within 80 minutes, they are forbidden from leaving the room. The movie’s tension and sense of dread builds to a crisis point, and Exam is a fascinating insight into those dangerously ambitious minds we’re so fascinated by in current times.

10. Right At Your Door (2006)

Slightly different from some of the more elaborate films on this list, Right At Your Door poses a ‘what would you do?’ question when Los Angeles is devastated by a dirty bomb explosion. Told to stay home and seal themselves off from outside air, Brad’s wife begins knocking on their door. Does he let her in and risk being exposed? Or does he keep her out, watching the consequences of those actions unfold on his own doorstep? The panic on both sides of the glass escalates, and we’re asked to ponder what we’d do if the unenviable situation were our own.

9. The Killing Room (2009)

Working with the same ideas as Exam, The Killing Room flips it on its head by putting a group of homeless people in a room and testing their resolve. With corporate meddling behind the scenes, the movie turns into an intense psychological study of human nature and the ways we react when our survival depends on answering various questions. Elsewhere, a woman conducting the experiment starts to question their methods, and things unravel, fast.
