You know you can be having a bad day and someone will walk by and say: 'Hey, I love you, Will.' That really cheers you up. That's a really lovely thing.

It would be great to be able to follow in the footsteps of Bill Murray. I really respect his ability as a comedian, obviously, but even more so as an actor.

If no-one comes from the future to stop doing it, then how bad of a decision can it really be?

I think anyone who has, you know, is in any sort of artistic pursuit, kind of goes up and down with the way they feel about their work. And I, for the most part, am pretty happy person. But, yeah. I go through definite periods of time where I'm not funny. I'm not good. I'm - I don't feel original.

On the set of an independent film you can tell that nobody is doing it for the money. Everyone is there because they love the script. A smaller budget sort of unifies everyone; it's a real team effort and that's amazing. But these opportunities just don't present themselves that often for me, so basically any chance I get to do something different I jump on it.

I left 'Saturday Night Live' without a film to go to, and I'd filmed 'Old School' while I was in my last season of the show, and that hadn't come out yet. I was a free agent, in a way, but I knew it was time to leave the show and test the water.

I love watching people be totally committed in a very real way to stupid situations. I find it's not so much trying to be funny, it's trying to be real in a messed up context. That's comedy to me.
