Obviously, I've been very lucky in general in my career, but I feel that I've been very lucky in terms of having directors come along at the right times who have taken me to the next level of where I needed to be.

There's a lot of work that needs to be done, and there's a difference between talking the talk and walking the walk.

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.

If I can make a career for myself after Harry Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.

I think I tried to steal a Mars bar once from a shop but then I went and put it back.

I don't really care about how I look.

Maybe it's a compliment to the film that you can't do that with it, that it can't be explained in 15 seconds.
