The script is really always the main attraction, and then there's whether there is an interesting character and great people around you. Those are the key elements that I look for.

There's a bit of pressure when you're reimagining something so iconic and loved. But the only way you can really do it is completely reinvent it.

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

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.

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

My favorite scene in this film was the flying car, because that was just wicked.
