I always wanted to go into acting.

I went out with people, but never anything too serious. It wasn't that easy. Now it's something I'm really looking forward to.

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

I’ve loved the whole process. From previews to rehearsals, I’m in the best company. I’ve done one West End show before this but the excitement here…it’s incredible. It’s been a real education working on this, I don’t feel worthy. The role is over the top, bold and ridiculous.

For me the stunts are so cool, they're one of my favourite things when we're doing the film.

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

I've always been quite a proud ginger so I couldn't dye it and betray the other gingers.
