I did have a Twitter account that I tried for a couple days, but found I had nothing to say. There are some interesting facts I could share, but I don't want to share that part of myself.

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.

As a human being, you know that there are some days when you'd rather not talk to anybody - but I can't really do that anymore without appearing rude.

Well, I'm a big believer in 'never say never.

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

In voicing so much is left to your imagination to create the world around you like that. It's really the essence of what's so fun for, I think, many people when they first start to want to be an actor, is that they realise they enjoy making up a world around them to exist in, a whole situation and a whole way of being. And even more so than theatre, animation requires that because there's just nothing to go on. It's in your head and your heart or it's not there at all.
