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.

As soon as I get my car I think I'll be going to the cinema more. Since I don't go very often, there are no films that are a must see at the moment. I usually wait till they come out on DVD.

People always tell me I'm nothing like my character. Well, hopefully not! He's a character who's very defined. He was purposefully written by Jo Rowling as very one-dimensional in the first few books, because you're supposed to hate him.

I'd love to be in Paul McCartney's shoes for a day. I'd love to pick up a guitar and write songs like he does. Or to experience what it might have been like to be a Beatle for a day.

I took the original stuff that I read as standalone [in The Flash]. I didn't have anything to refer to, so to me it was all new. It's delightfully simple, the show, but it has many moving parts. It certainly makes you pay attention.

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

You avoid the hype while you're working, you have to, but the premiere is the one night of the year where you can enjoy it.
