Well one of the times I did a stunt was in the devil’s snare room and they lifted me up on a harness and a safety rope really, really high, and they just dropped me down into the devil’s snare.

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

Before I knew there was going to be a film. I was the biggest Harry Potter fan. I read all the books.

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.

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

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.

I always loved acting, but it's weird to think what I'd be doing if this hadn't come around. It's kind of a bit of a fluke how I got into it, so I'm grateful.
