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.

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.

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.

I was such a huge fan of Harry Potter books. That's how I got into it. I had never really thought about acting or a career. I just wanted to be Ron, really. It was a very unusual introduction into the industry, and we learned so much. It's been a real education and an evolution. I really, really enjoy this.

It's not that I find it hard to meet girls - they do come up and chat me up from time to time. Sometimes I'm interested, I tend not to go for the prettier ones. I prefer the quirkier types.

Every time I come off-set, I am just like a normal kid again.

It would be quite good to be a Formula 1 racecar driver.
