I watched Animal House at the Indiana theater in Bloomington.I didn't do a lot of movie watching at IU...don't even remember where the College Mall theater was.
Do remember catching Cape Fear at the Indiana/Buskirk in school. Only time I can remember watching something at the Union was stumbling into a midnight showing of 3:10 to Yuma coming home from the Kirkwood bars one year when staying there.
Did watch Pulp Fiction at least 3-4 times in the theater in Dallas when that came out. Had one of those "two week notice" dead weeks where I had to sit in limbo for a couple weeks before I could start the new gig. Think I watched it back to back one Monday at the early matinees while everyone else was at work.
I also saw Carrie at the Princess theater and Let It Be (the original movie) at the Union theater, whatever that was called.
I think those were the only movies I saw at IU.
EDIT: I guess I did see Deer Hunter at College Mall theater.
