Somebody I love and have a huge amount of respect for once told me something that, to this day, I don't really think I understand. It was probably toward the end of Harry Potter, and they were talking to me about afterwards and that kind of stuff. And they were saying, "You need to think of yourself as a brand and you need to protect that brand." I just don't understand what that really means in terms of being an actor, and I also think I would find that a slightly soul-destroying way to look at myself.

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 feel very English in a suit. There's something about being in a suit abroad, particularly in America, that feels empowering.

I don't think that you necessarily need a certain type of background to take on roles. You see actors from very, very privileged backgrounds playing working class characters and vice-versa. I don't think your background limits you as to what you can do.

All it takes is for me to be seen chatting up a girl for [tabloids] to, you know, make up some crappy headline about me being a sex rat or whatever they call it.

I think of myself as being Jewish and Irish, despite the fact that I'm English.

Some actresses are just insane. I've never worked with a nasty actress - they're all absolutely delightful. But completely barking.
