Every day the Daniels [Kwan and Scheinert] would come up with some amazing solution and [make it easy] to put yourself in their hands. There's something really lovely about knowing you're working with directors who know exactly what they want and exactly what they're looking for, and they're not going to move on until they have it. That, as an actor, frees you up a lot because you can [try different approaches] and they'll only use what's appropriate.

I like the idea of not having to do stuff for the money, and if I want to, I can pick indie projects for the rest of my life and be quite happy doing that.

In terms of drama school, what that will give you that you won't necessarily learn on a film set is the technical ability - ie, projecting your voice and stage craft.

I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!

I might like to be an actor, but there are loads of other things I'm interested in as well, like music and writing and sports. I want to keep my options open.

It's mainly about working hard and proving to people you're serious about it, and stretching yourself and learning. The mistake a lot of actors make, particularly young ones, is allowing themselves to feel that they're the finished articles, the bee's knees, and it's not true.

I'm 5-foot-5, and I'll wear a big parka and put the hood up, and nobody gives me a second glance.
