I found out that you could audition by sending a picture of yourself and some information to Newsround.

I'm so proud to be part of Harry Potter and even prouder to be representing the gingers.

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.

If there is one thing of which I am most proud, it's that I made being ginger cool!

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.

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.

Itd be cool to carry on doing films, but when I was a kid I wanted to be an ice cream man.
