I've done a lot of movies based on real people, real situations, non-fiction books, magazine articles, life rights.
If you're going to spend two or three years of your life working on something, you've got to be making the kind of movie that discusses and influences the culture and is engaged in the world you're living in.
'The Social Network' was probably one of the two or three things I've done in my life that I'm most proud of. I'm not going to engage in what about it was disappointing. There's nothing about it I was disappointed in.
