I love theater. I think theater, when its done right, is the best, like a religious experience. When it is done badly, it's the worst thing. It's just an incredible experience.

Voices come to me but to maintain them is hard work. They go away just as easily, so I have to remember them and that takes work. With Sid, I needed to make sure you could understand what he is saying, his enunciation. Sometimes I couldn't even say my own name [his name] in his voice. It sounds like 'Shid', it sounds a bit like he has a lisp.

Well I was about to be expelled from school, I had been arrested and a teacher said: "Why don't you try acting, instead of distracting the class? Why don't you use your comic talent for something more productive?" My maths teacher suggested I do comedy and I decided to have a go. I pursued it after that. I was about 17.

I knew Linda Cardellini from when we did ER together - she was always great, such a cool spirit.

Bryan Cranston has got such an incredible light touch. He comes in egoless, but with bold opinions, and he wants to play. He wants to play. And that's what I've seen in great actors all my life and what I've always tried to nurture and keep in myself is that joy of playing.

I wanted to enjoy the process. I wanted to enjoy just being on stage and giving back and the feedback.

Self-expression is something that you've crafted, something that you've found. You've practiced on that piano for hours, you didn't hang out with your buddies, you didn't go after the girls, you stayed in your own little geeky room or you wrote for hours.
