I could be just a writer very easily. I am not a writer. I am a screenwriter, which is half a filmmaker... But it is not an art form, because screenplays are not works of art. They are invitations to others to collaborate on a work of art.
If you write interesting roles, you get interesting people to play them. If you write roles that are full of nuance and contradiction and have interesting dialog, actors are drawn to that.
I don't think it's very useful to open wide the door for young artists; the ones who break down the door are more interesting.
All these teachers and [screenwriting] books mean you see movies that have been worked over by more committees wielding more rules, that all originality and authorship is lost. That's why you're seeing superstars like Brad Pitt in THE FIGHT CLUB and Tom Cruise in MAGNOLIA. They're desperately searching for people writing and directing off-formula movies.
