It's always nice when someone says that they don't realize it's me on screen, but it would be strange to enter a one story while thinking of another character I do, which is completely different.

It was like in the film, when I was actually doing a take and wasn't quite sure of the context, and then in the completed film it works beautifully.In the end I didn't know why I felt so shitty doing it, and why it turns out great in the final product. I guess you have to live in that unknown.

It's not really about confidence. It's just something that isn't really in the vocabulary of what goes on at work. The writers write and the actors act.

I wanted to come to Chicago. I also wanted to do "Saturday Night Live." And then I got to a place where I didn't want to do those things anymore.For the sketch comedy thing, I got cast on "MADtv," and that will kill any man's desire to do comedy.

I don't mind being recognized, it's just that I have a bit of social anxiety, and this situation has increased it. The idea of having to be 'on' and social at random times can be difficult. I'll be out in the morning, someone comes and takes a picture, and then I discover I have toothpaste on my face.

When you have this long of a run [in The Big Bang Theory], you don't have to have something happen every episode. Like, Sheldon lost his virginity last season and in the first season he didn't even like girls. So I feel like you can earn that stuff. And that is really fun, because you get to find new layers. It's a testament to the writing.

There's also these moments when you're like, oh, I really want to do different things. Not instead of this show [The Big Bang Theory]. It's just a hunger to do something else, too.
