All I can remember about this movie is that a few people enter a building (parking building or something like that?) and then basically get stuck there because the building keeps changing? Towards the end, one (or more?) of them look outside from one of the high floors of the building and literally see themselves initially entering the building (weird time shenanigans?). The most vivid memory I have of the movie is the ending where one of them literally gets trapped in a 4x4 room with no exit or entrance.
