When I started Doctor Who Steven Moffat said, "That's it for the rest of your life." I'll be Doctor to a whole generation when they're 50.

When you think about it, we’re all different people all through our lives, and that’s okay, that’s good, you’ve got to keep moving so long as you remember all the people that you used to be.

Any actor worth his salt has a responsibility to reinvent himself from part to part.

I'm interested in how a lot of people pull objects together to form an environment that we feel reflects ourselves or makes us feel comfortable.

Being an actor is about having the courage to follow your instincts, and also having the discipline and dedication to sacrifice the things in your life that you need to sacrifice to get the best out of yourself artistically.

I am and always will be the optimist. The hoper of far-flung hopes and the dreamer of improbable dreams.

It's very rare that I play cool people. I'm not sure what that says about me.
