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.

What I try to do is give each actor an environment in which they can do their best work.

I love suspense movies, because in a sense they're the most dreamlike of any genre, and I'm sure I'll make another one.

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.

The challenge was the opportunity. When I read the first draft of Steve Kloves' fabulous adaptation - I hadn't read [Michael] Chabon's book at that time - what I was immediately captivated by was this group of characters that were at once so engaging and so messed up.

Roger [Corman] didn't actually hire me, though. I was hired by AIP [American International Pictures], the studio that made the picture, which was Sam Arkoff and Jim Nicholson. It was a great learning experience for me, because not only did I work on the script, but they hired me back to go on location when they were making the movie, to write new scenes and so forth.

Of course, Sam [Fuller] was like, "No problem," because he treated it like a newspaper deadline. We worked long hours, often very late into the night, in his garage, which had been converted into an office. It was freezing cold outside and there was no heat in the garage, so he had a little space heater over by his side and I had a blanket that he graciously gave me to drape around my shoulders like a Navajo Indian. And he gave me cigars, too, of course.
