It's been four years. It's been the best four years. It's been wonderful, it's been a privilege to work under Steven Moffat. But I think when you gotta go, you gotta go It's sad, I'm going to miss it. I'm going to miss Comic-Con as well. It wasn't an easy decision, but I dunno, you can't play it forever. And, look, they'll get someone amazing and brilliant, and that's the great thing about the show. It continues, and it will get bigger and better. And you'll forget about me.

I'm not handsome enough to be James Bond. Maybe a villain, though.

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.

The storytelling in 'Doctor Who' is quite universal.

I don't think anything could prepare you for whatever fame is. Fame is a very hard word to define cause it means different things to different people for different reasons so I never really think of it as fame, I think of it as part of the job.

History will only ever be partial, to a large extent history tells us what we think should be remembered and what should be forgotten, I find that really problematic.

As an actor, you'll have ten parts in 2015 - eight of them will go to the other actors above you and two of them you might be close to, and you try to make them as good as you can.
