I mean they [ Bradley Cooper, Zach Galifianakis] are both just really good guys and also they're both extremely funny in very unique ways. We made each other laugh an awful lot, and that goes a long way. And we also went through some hard times. I mean it was hard to make this movie [The Hangover].

I've always been into toys and kits and models. I'm kind of a toy nerd.

Getting any movie made is just like trying to push a giant boulder up a mountain, and there's so many moving parts. Obviously, there's the creative side, and then there's the logistical side, and they're both colossal.

People now genuinely respond to it and associate me with music. It's really fun.

One of the biggest breaks we had actually, one of the biggest, the hardest I laughed on the movie [The Hangover] was the baby was just doing ridiculous things and making hilarious faces. But I'm sitting there and I'm supposed to be having this exchange with Zach [ Galifianakis] and the baby is like staring at me with these huge eyes and acting, and just making the most cerebral faces, and I could not keep it together.

I didn't mention the tooth thing to anyone until it became clear that...we started to discuss just taking it out of the movie [The Hangover] because we couldn't find anything that worked and they couldn't afford to do a full like digital effect. So that's when I called my dentist and it worked out.

I loved the show Lost, in part because the writers were so nimble in how they would take things from previous episodes, that probably weren't created with any intent towards a larger narrative, and they would get woven into narratives in a really elegant and exciting way.
