I think what all actors share is that, somewhere down in your solar plexus, there's this fear that you're not going to be able to come up with the goods, that this is the one movie where you're going to look like a fool, and they should have cast someone else. And you feel ugly, and you've got three chins, and you've gained too much weight, and you're losing your hair, and there are so many better actors who could do this. But if you've got chops, what you realize is that everybody feels that way, so just show up and do the job.
