Be brave. Don't be afraid to be stupid.

There are great disciplines from being a sportsman that you can transfer into being an artist. The preparation, the sacrifice, the constant desire to improve.

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

I would be sitting in my flat watching TV, and 'Doctor Who' would be on with my flatmate there. I would have loved to share the fact that I was the new Doctor, but I couldn't. I was going mad. My dad was rather flabbergasted. When I told him, he laughed. He was excited, elated and very proud.

Read about a few men who wear (or wore) bow ties as an act of defiance, and check out a tie that makes a strong statement. Bow ties are cool.

I think that every artistic venture is a risk, and it has to be that way, so you do as much preparation as you can and make that as thorough as you can possibly make it, until you turn up on set. It's about taking risks, and some might work and some might not, but that's what makes it interesting.

I think that, if the world was a bit more like Comic-Con, we'd all be a little happier.
