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 really tried out for the part of Harry Potter, but they ended up picking me for the part of the enemy of Harry. Actually it is really fun playing the bad kid because it just has so many interesting qualities to it. And Daniel Radcliffe and I get along really well off set so it's really fun filming.

I like a funny girl. Smart. Talented. I like someone who is good at music - that always intrigues me.

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

I think it's pretty crazy to say you've been typecast at the age of 20 before you've even really started getting going.

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?

The best-looking girls don't do anything, they just sort of know they're beautiful, especially in jeans and a hoodie.
