I do think people do pick movies that reveal something about them that they aren't always aware of. If you ask them what kind of an actor they think they are, they'll probably tell you something different than what they've actually done.
Other quotes by Casey Affleck
I had a public school education - 3,000 kids when I was there. And there were a lot of teachers who would just sit there. You'd come in and sign your name and the teacher would just sit there at the head of the class and you would literally just have to stay in your seat for 40 minutes and that was the only thing you'd have to do in class.
