Mnemonic' is a play about memory.

I spent the majority of time at school trying to break the rules. I would climb to the top of buildings; I even burned a building down once - not intentionally, just because I was interested in fire. I remember going through the rule book, ticking off the ones I had broken and looking for the ones I hadn't.

I don't recall making a conscious decision to become an actor. I just remember winning a prize at a theatre festival when I was 17 and saying: 'Oh, that's what I have to do.'

I try to push a single idea to its absolute limit. So for all of those ideas that existed in the story, you attempt to find a physical realisation in the space.

The thing I'm most interested in is the nervous system. How do brains grow? How do genes build complicated nervous systems?

I'm happy to do voice-overs. I always have a good time doing them. I like to explore vocal nuance and accents and different people, different personalities. In a way, it is a lot more freeing than having your face up there.

A lot of rappers think they better than me because they saw me broke, going in and out of studios, and couldn't pay for studio time.

I was 12 when I decided that I wanted to see myself on the big screen.
