10 Terrifying Horror Movies Based On Human Experiments

10. Exam

Sometimes, you don't need a considerable set-up, wide array of locations or massive amounts of plot to keep a film engaging. Exam proves that you can base a movie in one distinct location, allowing the narrative to move forward through the characters' interactions and still generate a tense and scary atmosphere.

The movie follows eight strangers who have all turned up for an exam - as you could probably guess. This group is locked into a singular room and given a simple question, with the person who answers it winning a prestigious and highly sought after corporate job. However, it doesn't take long for the scenario to become dangerous as confusion and chaos erupt.

While this concept doesn't make the movie sound too frightening, it certainly is. The characters' complete paranoia is accented by the claustrophobic space, which entombs them in their irrational thinking and causes the strangers to become violent and unpredictable. This is only fuelled further by the competitive aspect of their task.

The idea behind this experiment is fascinating, as it looks to examine how people respond when given vague instructions in a competitive environment and are left to their own devices. As was probably expected, it devolves into anarchy.
