I'm too sensitive. I could not show up to a murder scene and do anything like that. It would break me instantly.

With Submarine, when I came out of school, people were so lovely and supportive. And you don't get that experience very often. It felt like a family on-set. So Submarine changed so much for me.

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 was 17 when it was being filmed and so I was at an age where you are learning a lot about yourself. I came out of school to film it, and I hadn't been having a good time in school before that. I get quite shy around big groups of people. If I meet people, especially my peers and people my own age, I always struggle because I've always worked with adults and they have a tendency to molly coddle you a bit when you're the youngest on-set.

When I'm filming something, I quite forget that it's all still got to come together and be edited. I'm so engrossed in trying to do the best I can on a day to day basis that I forget that people will see it and judge it.

That's part of this industry. It's hard a lot of the time, especially when you get knocked down a lot. There's a lot of criticism and it's always in the back of your mind that you may never work again.

There was a huge period where I was filming and studying. But then we went into summer and it became easier. I did find combining the two difficult and I haven't figured out how to do it effortlessly just yet.
