There were two auditions for 'The Social Network,' one with Aaron Sorkin and one with David Fincher. I was a nervous wreck. I was like, 'Okay, how do I hold the paper without my hands making it shake?'

There's two tiers of science fiction: the McDonalds sci-fi like Star Trek, where they have an adventure and solve it before the last commercial, and there are books that once you've read, you never look at the world the same way again.
