Hi. I'm Willem Dafoe, and this is the timeline of my career.
I never really decided I wanted to be an actor. I always kind of thought I'd end up doing something differently. And then enough time passed where I thought, I guess I'm an actor. I've been doing this for a while.
I went to school for a little while in an acting program. But I dropped out very quickly, and I was reading about people like the performance group, the Manhattan Project, Grotowski, Robert Wilson. So I went to Mecca, which was New York.
There was part of me that thought I would try to be a traditional actor. But I kept on finding myself going downtown, going to loft performances, sing, dance. And I got involved with a company called The Wooster Group that I ended up being with for 27 years. And that was my day to day life. My first IMDb credit is Heaven's Gate.
