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.

I'm sure I cause just as much consternation for editors as any other actor, but it definitely makes me feel more comfortable understanding how and why all the different camera setups exist.

Vulnerability is huge. I love to see that in characters. It's something I feel like a lot of my comedic heroes have always done.

Alcohol causes conflicts, firearms resolve conflicts.

As an editor, you're constantly dealing with the best way to convey an exchange between two people. So when I'm shooting that, I'm just aware in the back of my head what an editor might want. And also, the problems editors run into when trying to edit performances - it helps me head that off at the pass a little.

We did some camera tests blacking it out, we made a prosthetic with a gap in it, but that made me look like a donkey, so I vetoed that right away. And then I just finally called my dentist and said, 'You know, I've had this implant for 20 years. What's it involve in taking it out?' And he said, 'It's actually not that big a deal. We can do that.' So we took it out and I was toothless for three months, for the run of the movie [ The Hangover] .I take my job very seriously.

It's incredible how big a part of my acting career music has become. I get asked about it all the time, and I love it. It's one of my favorite things, and I'm so glad that I get to sort of work that in.
