I'm quite severely dyslexic so I struggle with acting in certain ways. I always have to put in triple the amount of effort, which would always frustrate me a lot. I suppose that some people can just look at a script once and know it. That's not me. I really have to spend a bit of time with the lines. But it's my job and I've got better and better at it. If you're learning a lot, things start going quicker. Doing the lines with repetition and you just get it in your head somehow.

I love the challenge of playing characters forced on life-changing emotional journeys. To work on a project with Billy Crudup and Sam Rockwell is just a dream come true.

Being blinded by young love. I remember the feeling, when I first fell in love - you don't see the world the same way that other people see it. You don't see the same boundaries.

You can have a great script, or a great director and a bad script, and get a great movie. Nothing really guarantees anything.

I wanted to become an actor. I went to Guildhall School of Music and Drama, which is one of the main drama schools in London where you go when you are older. But I was doing the junior one when I was a kid. And some friends there had agents. I was fourteen and I was like, "I want an agent! It sounds awesome!" I had no idea what that was. I thought those guys looked like men in black. They were hanging around in suits all the time. So I luckily got a very good agent in London and started auditioning. And then when I was 16, I got my first film and I've been working ever since.

It's really important to take time for yourself because if you don't know what it is like to be a real person and spend time with a sense of normality, how can you play normal people in films?

The negative about acting is that you have to spend a great deal of time away from your friends and loved ones, but it's not like working a 9-5 job and only having two or three weeks off a year. I may not have seen my girlfriend for two or three months, but then we can spend two or three months together solidly.
