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.

You know, when you're in your twenties you use a great deal of symbolism. You somehow think that a character standing beneath a cross is more interesting than a character standing underneath a billboard, but when you get a little older you realize that there's not much difference.

I would not have made any of my films or written scripts such as Taxi Driver had it not been for Ingmar Bergman, What he has left is a legacy greater than any other director.... I think the extraordinary thing that Bergman will be remembered for, other than his body of work, was that he probably did more than anyone to make cinema a medium of personal and introspective value.

There's something wrong - the performance, the weather, the set design, the lighting. Something is not working. And so you say, "Give me 10 minutes." When you're first directing, you're terrified. But when you've been in that situation enough times, you know that under pressure, it will come to you.

Don't ever let the viewer settle in and get ahead of you.

Screenplays are not works of art. They are invitations to others to collaborate on a work of art.

Those artists who say that somehow therapy or analysis will thwart their creativity are completely misinformed. It's absolutely the opposite: it opens closed doors.
