Is this the movie?
Where Stellan talks to some guy and tells him a story about some guy getting his dick pumped full of wax?

Well, it is that movie, and I do hope it's not the only thing you took out from it!
By the way, the "some guy" he's talking to is Paul Bettany. And they both do a fantastic job with these characters.
I love this movie!
Well it was about the only scene I really saw when I was flicking through channels. The only other thing I remember is Sean Penn's brother walking around with a very simple look on his face as though he was handicapped.
