My heroes are Bill Murray and Dustin Hoffman. Those are the two actors that both do comedies and dramas, seamlessly. Also John C. Reilly and Philip Seymour Hoffman. They're all just great actors, neither comedic nor dramatic. They're just great actors.

If you're trying to make someone happy, you gotta try and make them happy. If you're trying to have a normal conversation, you've got to have a normal conversation. If you're trying to make them sad, you've got to make them sad. I think that's how you get real performances out of people.

The comedy really comes from how badly you want these characters to succeed and with a comedy that's often hard.

'Funny People' is my favorite performance of myself to date. Even though it's a comedy and there are serious moments, I really felt like Leo felt like a real person. It didn't feel like I was playing myself. Whether it's a comedy or drama, I just try to make it as realistic as possible.

When you're looking for stories or movies usually the great stories are about people in their 30s or 40s because they've lived more life and they're usually accomplishing more incredible things. But when there's an interesting story about someone that's your age, you immediately - especially when you're younger - are like, "Wow that's crazy! There's not very many of these."

I'm too judgmental of other people putting themselves out there in any way, I guess.

You just have to be strong and don't be stupid; freedom of choice is a big responsibility.
