Put simply, there are many people who want to make movies and very few opportunities for them to do it.
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.
I did it [photojournalism] 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. So I stopped doing that and wrote some screenplays on speculation, because even though I wanted to direct, to direct you need a lot of money.
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.
There are many people who want to make movies and very few opportunities for them to do it. I had a checkered early career with a lot of very unhappy experiences where pictures got taken away, re-cut, re-titled... all the nightmares one hears about. Consequently, it's so gratifying to then make a picture that's successful and gives you leverage to have better circumstances than you've ever had, before the next time out.
