I'm a keen musician. Me and my mates have a great times jamming and recording stuff. We have a great band behind us and have turned my nursery-rhyme songs into quite credible pieces of music.

I like my ladies lady-ish, feminine so to speak. I love jeans and hoodies, but the idea of being an ultimate tomboy does slightly confuse me.

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 already love the idea that Barry has a colleague. It seems like a love/hate thing between my character and his already. They work together, so they clearly have some tolerance for each other, but they're just ruffling each other up the wrong way, constantly. I don't know whether that will lead to him being suspicious of Barry's identity or whether he'll have some clash with The Flash.

The Japanese fans always send weird things.

It's remarkable to see the advancements since the early days of [Harry] Potter with putting LEDs on everything, pointing sticks and measuring. Just archaic stuff. Now, it's like one guy with a laptop.

It's like in politics: You can have great intentions for the world, but if you're not a good speaker and if you're not the sort of person that people can intimately link with, then it makes it very easy to say, "Well, they're not a nice person."
