I remember my first scene with Alan Rickman, and I was anxious because he is a slight 'method' actor; as soon as he is in his cloak, he walks and talks like Snape - it is quite terrifying. But I really wanted to talk to him because 'Robin Hood' was one of my favourite films.

The idea of being famous is a lot better than the reality.

I used to have some fish, some nice little carp, but they got too big for the tank. I don't have any pets now.

I bought a lot of rubbish things that kids buy: skateboards and clothes and typical teenage stuff.

One of my first things I was fascinated with when I got on set was how does Grant do all this Flash stuff? it looks so good as the end product, but how does the special effects team work? How does the visual effects team work?

It's such a cool group of people that it [being a part of the DC Universe] feels like, for lack of a better analogy, being back on something like [Harry] Potter. We're working with a really tight, talented family.

Nothing's really changed since the Harry Potter films came along.
