"Escape room movies, as a category, blend elements of survival games and isolation horror films. At its most basic, an escape room movie is about a group of people locked inside a room or building who must solve puzzles or riddles in order to go free. Most escape room movies heighten the tension by adding time limits, traps, and a death penalty for failure, but those additions aren't technically required.

Escape room movies can be made relatively cheaply since all you really need is one set, a few props, and just a few actors. For that reason, a large proportion of movies in the subgenre are low-budget and independently made. That's never a bad thing though. Collected here are some of the best movies, from no-budget to big-budget, that fall within or very close to the escape room criteria laid out above."
