Quote:
"Screenwriting is my favourite part of the filmmaking process because everything is still possible and not mitigated by the exigencies of production. I find it to be a joyful process as well as agonizingly lonely. It is so magical, later, to have dozens of extremely talented people make those ideas you've had alone in a quiet room become tangible and real."
