I was in the bath at the time, and my dad came running in and said, 'Guess who they want to play Harry Potter!?' and I started to cry. It was probably the best moment of my life.

Once Now You See Me proved that that tone could work, which I'm sure was a nightmare for them in post - is this too serious? Do we have to say that magic really does exist or not? - I can take that and have fun with the tone that they established.

I am very critical! I hate watching myself but I know I have to because I'm going to be asked so I need to have some sort of semblance of what the films with me are like. But it's not an enjoyable experience watching yourself. I hate it less than I used to but I still don't enjoy it.

I want to write and direct, but I don't think if I did it for 100 years I would ever come close to putting something out there that gives a feeling of all-encompassing and joyous.

There's never enough time to do nothing!

I certainly want to establish myself as an actor in my own right, rather than being just the actor who plays Harry Potter.

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.
