I've seen his earlier stuff, I was so surprized when he became this big name, I have purposly avoided any movie with him in it just because I don't think he has proven to be any good.
UP, you need to watch In Bruges. It's a great movie and Farrell did a really good job. I think he does better when they let him talk with his normal accent.
Tom Arnold certainly ranks amongst mankind's worst atrocities. Granted, his cultural relevance was never very great and he's been gone from the scene for many years now.
