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.

We're not used to seeing movies, especially with physical action, when it isn't the man who comes in to save the day.

On the surface, Wonder Boys seemed like such a departure from L.A. Confidential - it's funny, it's contemporary, and so on - and yet at a certain point, I had a feeling that reminded me how I felt when I was shooting L.A. Confidential. I analyzed it for a while, and thought about how emotionally involved I was with the characters. Then I realized that in both movies, there are three main male characters and one female, and all of them are struggling to figure out what they're doing with their lives, independent of each other.

Initially, it connected with me when I was a kid, seeing a lot of movies while growing up in Los Angeles. And Sam's [Fuller] pictures are an expression of such a distinct voice that he was one of those filmmakers who made me aware that there was, in fact, a real presence behind the camera that was telling the story, as opposed to actors just presenting it.

I very much had wanted to do a picture with more humor than what I had been allowed to do earlier, which is what attracted me to Wonder Boys so much. I found it funny in a very serious way, which is the best kind of comedy.

I had always wanted to tell a story that was set in Los Angeles in the '50s, because that's where I grew up, and it was the city of my childhood memories.

In L.A. Confidential, it was great to surprise the audience with Guy Pearce and Russell Crowe - two Australian actors that they didn't know at all - and let people discover them through the course of the film.
