harry potter, LOTR, don't demand that I watch them anymore, but they're still fun when I do. Galaxy Quest, yep. Most any light/romantic comedy will do, even formulaic ones, especially if its one of those blatant cross-marketing of contempoary music so it's more like a music video. Just about anything quietly British. Death at a Funeral with a hysterically acid-tripping Alan Tudyk is a current fave. Awesome visual effects makes for good accompaniment to working with two-tone text or code all day. The Mummy is great for this, as is Golden Compass. I don't usually like obnoxiously loud movies as background noise, but a taste of kick-ass heroine is nice, so up with T2, Aliens and Aliens Vs. Predator. :)
