The Big Bang Theory' has completely changed my life.

I've grown out of dancing in my car - is it sad? Or I've just become a better driver!

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.

You think of it [voicing] as something where you not only don't //need// your body, but you don't even have it to use! There's nothing you can do with your body that's going to show in the final product. Maybe that's all the more reason I used my body so much to get whatever noise or sounds out of it I could. When it was needed to keep the energy up I found myself almost running in place! It is very physical.

Realistically, there is a danger, of course, when you're going into someone's living room as the same guy every week. But I don't fear it because, I mean, there's really nothing I can do about it. I can try to combat it through the work, and maybe make sure I don't do Sheldon 2.0 in any other projects. But it's just really hard for me to find any negative side effects from this experience.

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 have this thing. I've always been uncomfortable going to any party where people don't understand why I'm there. One of the best things about partaking in a show like this is, when I show up to events and parties now, they know me. I don't have to hear, 'Oh, you're an actor? Have I seen you in anything?' anymore. I used to have to start listing things off of my resume'. It's really nice not to have to do that anymore.
