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.

Even though L.A Confidential box-office was a fraction of, say, Titanic or the Grinch movie, it finds its audience and will continue doing so for who knows how long, because of the basic thing we love about movies, which is storytelling and performances.

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.

I had written the script a few years earlier for Paramount, then later got hired with Sam [Fuller] to write an entirely new script that he was going to direct. And that was one of the great thrills of my professional life.

I never intended to have a career as a journalist, writing about people who make movies. I did it as something that was really rewarding to do, given the opportunity to express myself about something I cared about, and also to learn a lot by watching filmmakers I admired. In a sense, it was my film school. After doing it for a few years, I decided that the time had come to get it together and do some work of my own. Even for a cheap movie, you need film stock and equipment and actors. Whereas to write, all you need is paper and an idea, so I felt that writing might be my stepping stone.

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.

I was a journalist and wrote about filmmakers, but I didn't review movies per se.
