The paparazzi were outside the theatre every single night, but we came up with a cunning ruse. I would wear the same outfit every time - a different T-shirt underneath, but I'd wear the same jacket and zip it up so they couldn't see what I was wearing underneath, and the same hat. So they could take pictures for six months, but it would look like the same day, so they became unpublishable. Which was hilarious, because there's nothing better than seeing paparazzi getting really frustrated.

And the people I'm best friends with on the films are not generally the actors.

Stage is much more intimidating than going before the cameras, because you can really screw up, and can't do a retake.

I've always thought that as long as directors and casting directors don't see me as just Harry Potter, I'll be OK. People have shown a lot of faith in me, and I owe them a huge debt. They're letting me prove that I'm serious about this.

The stories I'm interested in are challenging ones, and maybe that requires a little bit more of you. I love my job and I want to earn the right to do it every single day.

I'm not clumsy, I'm just accident prone.

I always saw Michael Gambon wearing madly psychedelic socks, and I always thought that's it is one of the few areas where men can really express colour and have a bit of a dandyish quality to their outfit.
