When I write, I see a movie playing in my head. The role of the
screenwriter is to step back and let the directors have their head
during the process. Sometimes they're amazing -- often they make
wonderful additions, as do the actors -- and sometimes the films are
different in a way that you wish they weren't. I think at some point or
another, every screenwriter feels like they would like to fall on their
own sword, and try to get it to come out the way that they saw it.
