I'm awful at karaoke, but if I did have to sing, I'd go for my favourite Frank Sinatra song 'I've Got You Under My Skin.' The fact I love Frank is my grandfather's doing: he drummed it into me from a very early age that Frank Sinatra is God.
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.
If I could film, we'd film every episode of 'Doctor Who' in New York. I have an affinity with the city. It has some wonderful locations and it is devastatingly vast and huge. Central Park looks amazing on camera.
It's hard work, 'Doctor Who,' but let's be frank about it, I'm fortunate to be rewarded in the ways that I am. I don't just mean financially, I mean the nature of the part and everything that comes with it.
I constantly watch 'The Simpsons' and an English cartoon called 'The Raccoons' and 'Gummi Bears.' I was obsessed with ninja films, and the 'Teenage Mutant Nina Turtles,' I used to love that as well.
I quite like the idea of family. That's probably the greatest achievement in the world. I've got a lot to achieve workwise - I'd love to direct - but family would be good.
If I see a spider in the flat, I try to get a cup and a piece of paper and throw it out of the window. I can't kill them because they're good for catching flies.
For clothes, I like Dover Street Market and Acne. For vintage, I go to Mint just off Seven Dials. For shoes, it's Church's and Russell & Bromley.
I asked for a piano in the TARDIS, but it hasn't happened. I'd love to see the Doctor rock up and play, but it'd have to be done in an inventive and silly way.
If I was making a tea advert, I would want to communicate about tea is that it can console you, it can start your day, there is the warmth and the ritual, and you can share it; you make someone a cup of tea and you offer it to them.
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.
I think there's an interesting contradiction of having a young face and an old soul. There's something funny about it, and it also allows you to reinvent being old.
Kids should feel afraid of 'Doctor Who.' All the adults I've talked to remember fondly being afraid when they were kids. That's part of the reason they remember it and love it. And if you're afraid in a controlled way, you sort of appreciate fear in some respect.
If you want to give it a good go, you've got to make some sacrifices and be as dedicated as you can be. Particularly with 'Doctor Who.' It's two or three hours of line-learning a night.
Sometimes when you lose your mobile phone, even though it's frustrating, it's sort of rewarding in many ways because, though we do rely on them a lot, we are not reliant on them. The world continues without.
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.
Every two weeks on 'Doctor Who,' the set is completely different, the world is different and there are new actors coming in. So, it's constantly surprising, and it's a pressure that you relish, actually.
So many more people recognise you and want to take up a moment of your time for a photo or a hello. You try to deal with it with grace and a degree of humour, because what's the alternative?
