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.

I've just started school again, and it was a bit strange to start off with; it took me three or four days to get used to it. My friends have been great, they've been treating me normally.

I've known Emma Watson since she was 9, we've watched each other grow up, formed this sort of brother/sister bond, and suddenly I'm leaning in to kiss her. Well, it felt completely wrong... but, you know, you try to sink into the character and divorce yourself from it. We ended up laughing hysterically afterwards.

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.

The truth is that Ron is my hero. He's always there for his friends - sometimes belligerently, but there nevertheless. He's also the comic relief in stressful situations; the funny guy with a great one-liner. And no matter how scared he may be, he will put aside his fears to support and protect the people he loves. To me, that represents true courage.

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

I'll always be the ginger one from Harry Potter.
