I’m trying to remember a move I saw like 10 years ago, maybe a little more or a little less.
There was a bunch of people locked in a house. All the movie happens in that house. It was a modern house that had a somewhat dark blue lighting. It always had that blue tint I think. I think they need to kill each other if they wanted to exit or something like that. It was probably an indie film, it seemed to have a low budget.
