I do get one chance to dance [in GoF], I had to dance with Maggie Smith. That was the only dancing experience I had, which was actually quite enough really.

I am a really big Harry Potter fan and I've seen all the sets, I've lived Harry Potter and I don't think it's destroyed the books at all, I think it's really spot on.

It's always at the back of my mind that acting might come to an end for me when Harry Potter finishes. I don't know if I'm good enough to have a long career. I've got a bit of an inferiority complex about my acting. My self-esteem is quite low in that sense.

There's a real sense of freedom now. It's a good time to finish, I think. As much as I'm going to miss it I'm ready to move on and do different things.

Like one time I was a fish in Noah's Ark and now I'm in Harry Potter, a big step.

Harry Potter has been a fantastic experience and the fact it has made stars of us all is unbelievable at times - it really is magic of a sort.

After being in Harry Potter, I believe a bit more in magic than I did before.
