I'm not much for the stuff outside the movies (animated series, etc.), but I'm crazy about the movies, so much that I try to get my hands on any commentary and draft I can.
I'm also mad about the 1950's. Anything to do with the 1950's: poodle skirts, rock'n'roll, the native dances and the song (there's a hint here), fountain pens, slide rules, vacuum-tube computers taking a building all their own, and you get the drift. The 1950's were a gay time. (There's a deleted scene in Back To The Future I that plays on this joke.)
