Jekyll is quite me: young man; polite. But being able to play Hyde was quite fun, to create a character that's nothing like me. I quite enjoyed creating a new character like that: he had a different voice; physicality; mannerisms. Everything had to be thought about. It was a real challenge.

I remember when I was younger, we used to read the Goosebumps books that were absolutely terrifying.

Maybe it's a bit snobby, but it's as if you're a proper actor if you do stage.

My mum asked me what I prefer, and I said, 'I never miss film, but I miss theater.'
