These kinds of movies seem to have a great ratio for me. The first one that comes to mind, and the earliest is "12 Angry Men", as well as: "Le Trou" - a great prison movie. "Rope" is a good one that is in real-time (not as good as the aforementioned though)
sharebed - just like it sounds. a hipster couple stays home and goofs off in bed all day. i liked it.
melvin goes to dinner - bob odenkirk directed film about people going to dinner. it's been a few years, but i'm pretty sure they never leave the restaurant table. wouldn't swear on a bible, though.

I heard about "Cube" in the late 90s from a neighborhood friend.. He described some of it, and I've been wanting to see it.
shareI think you will love it. Cube inspired the Saw series and was one of the first films in this category. Cube 2 (2002) was worse but you may check it out too. Cube Zero (2004) is a prequel - my least favorite in the series.
shareIf I didn't have a few errands today, I'd see it... Maybe tomorrow :)
