John: (On his character in the movie "Me and You and Everyone You Know") It's not maybe very flattering to think that you're suited to a part like this. But sometimes you feel like you can connect with a part in a way you don't think anyone else could.
John: (on the roles he gets)I do all kinds of roles -- nerd, psycho, nerd, psycho, nerd, psycho -- and occasionally someone kind of normal. It's weird, when I lived in Austin I was always cast as pretty normal people. But when I moved to Los Angeles I was immediately branded a psycho.
John: (On his inspiration)I went to a performance of 'The Crucible' at the Guthrie when I was a sophomore in high school, and I knew right away that that's what I wanted to do.
John: (On coming of age in Minnesota)I saw Harold and Maude, listened to Tom Waits and read "On the Road" and just decided - all at once - to get out of there."
John:(On acting) You never really forget who you are. If you did, you'd need to seek some professional help.
