I used to love ninja movies. That was my thing.

I think expectations of Doctor Who should always be high, because it's a show that must always progress and get better and better.

I am terribly clumsy, so there is a plethora of walking into lamp-posts, falling over, dropping things, and ruining sofas.

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.

At university I had a big coloured scarf and people would often say, 'All right, Doctor Who?' And, I thought, I rather liked that notion.

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.

I am a fan of a bright sock. They're bold.
