So I’m not sure if I remember all of it but I think the premise of the movie was these two men were to be confined to two rooms where they could see each other (separated by a glass screen) and they could have anything they wanted they just couldn’t leave the rooms. I saw it between 2000-2010 and I don’t think it was a very popular movie but I remember them first thinking everything was great and as time went on they slowly went mad-trying to attack each other through the glass, throwing things, etc. I think there was a specific rule against no contact with females or something either? The whole thing looked like it came out of an early 2000 music video where the rooms had lights coming out of the walls and not from lightbulbs in the ceiling. Some parts may be inaccurate as I was very young when I saw it.
