But we knew the characters pretty well because we were all big fans of the books.

But I like all the books. You've got to read them all to get the complete Harry Potter experience.

I was always a big fan of the books and over the years I've become quite attached to Ron and we've meshed into the same person, really.

They were just kind of simultaneous - the film ending and the sets being destroyed. I was struck the first time I saw the Great Hall become a big pile of burning rubble and getting scattered around. It's really quite shocking for the fans.

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.

I'm shorter, I don't have as many freckles as Ron, and I can't do magic.
