I watched this film at least 8? years ago; group of random people in a white room have to kill each other off to be the last surviving one. the ”survivor” walks out the room to realize they’re in a new one and have to do the same again. It’s not ‘The killing room’ that keeps coming up when I try to search.
Can someone please put me out my misery and help me with the name?
Could be ‘Cube’ (1997)
I am guessing: House of 9 (2005) – http://www.imdb.com/title/tt0395585/
