I mostly make R-rated movies. To make a movie that one day if I have kids or my nephews want t watch, I can show them without being put in prison. It would be really nice.

'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.

21 Jump Street is great. I just made that, and produced it and was a writer on it. It's starring myself and Channing Tatum, and maybe some surprise guests.

You really feel an obligation to someone when they're trusting you to do something, and you promise that you'll come through for them.

Sometimes what happens I think is that actors finish a movie and they go, oh my god, I'm never going to work again, even big huge actors, and so they'll take something thinking that something else will never come along. But for me, I freak out - because I'm a bit of a workaholic - the second I finish a movie going oh my god, what am I going to do, but I can start writing the next day so it doesn't force me to make a bad choice acting-wise.

I grew up with baseball; I played in Little League and went to games with my dad. But I, as I grew up, became more of a basketball fanatic than a baseball one.

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