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.

Whatever grade I get, even though I do try my best, I'll be happy with. I feel so lucky to have done all the jobs I've done to this point. So, if I continue to work it will be amazing. But I'm going to see how it goes.

There are loads of amazing actors in the UK and only 2% of them are in work, which is crazy.

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

You have to remain positive and just try your best and part of that is doing things that continually surprise people, including yourself, so that you don't get pigeon-holed.

With 'Submarin', Richard [Ayoade] gave us a lot of freedom and he really helped us. He's so amazing. It really changed things for me and brought my love for filming and working with people to a completely different level. It really was a wonderful experience.

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.
