In L.A., I have more of a yard existence, and so I enjoy walking my two little dogs in New York - one's a Maltese and the other's a Shih Tzu.

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.

It's a shame, but every time I get something scientific in the script, I read up to find out what I'm talking about - but then I'm on to the next script and it's forgotten.

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.

Every time I think about writing, comedy doesn't interest me in the slightest. I can play comedy, but I don't think in terms of comic dialogue.

I grew up with two different parakeets - one that lived for five years, and one that lived for 13 years - so I always had a bit of an attraction to birds and it's an oddly good fit to be in a movie about birdwatchers.

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