"The number one metaphor I have in my mind for writing a screenplay is that...you're trying to climb a mountain blindfolded. And the funny thing about that is, you think, 'Okay, that's hard because you're climbing up a rock face, and you don't know where you're going, and you don't know where the top is, you can't see what's below you...' But actually the hardest part about climbing a mountain blindfolded is just finding the mountain."
