There's no audience to wonderfully get in your way when you're doing a single-camera anything, whether it's a sitcom or drama or film. And I do mean that in the best way.

I'm also a big American Idol fan. I think it's just great fun.

I think in any form of acting, you're always well served if you've done theater.

[Voicing a cartoon] feels like going down a mysterious but joyful black hole. Once you relax for 15 or 20 minutes, and really go, "I don't care if I look like an ass," it's really fun to see what happens. You know that nothing is being visually judged.

I try to master every facet of a character in order to build a safety net for myself, so I can go on to take more risks to create someone really distinct.

Playing Sheldon is just heaven for me. I realize how enormously lucky I am to play a role that makes me so incredibly happy. As I told Chuck Lorre in a Christmas card a few years ago, I'm living a version of the dream.

I don't think the jet-setting life is really for most people.
