I saw this film on the IFC at two thirty in the morning, and I didn't see any introduction for it, just the opening shot. The entire film was quite excellent and very suspenseful, with a killer climax. I doubt this is available commercially, but if you see it on tv, be sure to check it out. When I checked the other user comments I noticed it's by Cube's director - knowing that makes the similarities between the two quite obvious (set of people in one room with no clear directive).
