A new Spanish film features four rival scientists struggling to solve logic puzzles before the walls of the room they're trapped in squish them into jelly. Fermat's Room combines elements of Pi (brilliant new untried math theorems) with Cube (deadly rooms that'll kill you unless you figure out the puzzle) in this new movie that'll have you wishing you paid attention back in algebra class. If the classroom was about to kill us, you can bet we would have. Fermat's Room [Variety]
