Can't possibly be surprising that I'm the first to reply on THIS one.
I love this movie. Dean Stockwell was brilliant in it, and I'm glad he got an Oscar nomination (back when comedic roles were intelligent enough to warrant Oscar noms)... But I recently saw Fish Called Wanda, and I'm not terribly disappointed that Dean lost to Kevin Kline (I like Kevin, too).
This movie is really absurd to the point of hilarity. I miss movies like it and Wanda, the kind that are intelligent while being hilarious... Wish more comedies were like that today.
I give this an A-.
