I would miss months of school and then return with bright blond hair. Needless to say, there was bullying. I wasn't beaten up daily, but there was name-calling and jealousy. You have to bear in mind that 'Harry Potter' wasn't cool. I wasn't part of the 'Terminator' franchise.

And to me, fame is not a positive thing. The idea of being famous is a lot better than the reality. It's fantastic when you go to premieres and people cheer you, but it's not real. And it's totally not my approach to get my name on a club door just because I can.

Whether it's acting, directing or writing, I want to be involved in the film industry for the rest of my life.

It's shocking to say, but the cinema is quite a while away from me, and I haven't got a car yet.

When it was offered [a role in The Flash] I just thought it sounded like the perfect thing that I would want to do. Then they announced it online the day after and I was terrified, because I hadn't read anything, I hadn't shot anything. What if I'm awful? What if they fire me on the first day? But what I discovered was a bunch of really happy actors who want to make the best show possible, because it's fun. Not for any other reason.

I am looking to get into the grime rap U.K. scene.

Nothing's really changed since the Harry Potter films came along.
