^ A week or so ago I slept through Casablanca in my Intro to Film class. Most of the films we've seen so far are interesting to one degree or another, but I've never seen Casablanca and it just doesn't appeal.
I don't have to worry about it being on a test because everything in the course is take-home essays; if need be I could rent the DVD and watch it.
Casablana is a "How to write a screenplay" movie. I you like movies, you won't regret watching this.
I kind of had a similar thing with Citizen Kane, but instead of sleelping through it, a couple of guys in the class and I skipped it to go skiing. I don't regreat skiing, but I do regret not watching the movie. I never saw Citizen Kane until 10 years later when my friend got it for me as a gift. IMO, it's one if the finest films ever made and I was kicking myself for going so long having never seen it.
I've only ever walked out of movies where other people are talking or had brought babies.
