I had a very short time on that film [The Possibilities Are Endless] and it was quite strange because the process was kind of like a documentary, which was different for me. The way everything was filmed was very casual.

I think you have to be extremely strong to be in the police and I couldn't do that at all. I get nervous when a police car is driving past me when I'm in the car, pondering what they're doing or going to.

I didn't know I wanted to be actor when I was four.I did it at the beginning because my brother did it before me and it was a hobby. I didn't mind doing it. But then it got more serious.

I wanted to go to university and experience something that I felt like I'd missed. I wanted to be around bright, intelligent young people who were learning about themselves.

I've done a lot of things for a very young audience so far, such as The Sarah Jane Adventures. I'm tiny and petite and I look very young, so I tend to attract those kinds of roles.

Going forward, anything that Richard [Ayoade] asks me to do, I would be so honoured... even if it's sweeping the street because he's such a great person and a great friend.

When I was 12, I did my first sort of speaking role. But I wouldn't say I had a passion for it from the start. It developed as I started to become a bit more mature.
