Here [in Wonder Boys] I had this group of characters where you didn't know which were the important ones or what direction they were heading.

I thought, "If I could bring these characters [Wonder Boys] to life and lead the audience to react the same way I did, this could be a really special picture." Then I read Michael's [Chabon] novel and got even more enthusiastic about it.

From my point of view, when I was thinking about the prospect of [Michael Douglas] in this part, I wondered if he would go all the way with it. The reason I was concerned is that, oftentimes, actors - especially movie stars - when they're playing a character who might be perceived as unattractive or eccentric, will wink at the audience while they're doing it.

Movie stars exaggerate certain things to let the audience know they're just playing a character, as if they're saying, "Look at me, I'm not really an old man, I'm just playing one." Or "I'm not really a homosexual, I'm just playing a gay character. Or an alcoholic. Or somebody who's mentally impaired." They often do it very successfully and win awards for it.

I look for characters that interest me, and a story that keeps me involved and makes me want to know what happens next.
