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.

I'm not an easy person to love. There are lots of times when I'm a very good boyfriend, but there are times when I'm useless. I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things.

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.

As an actor, there is room for a certain amount of creativity, but you're always ultimately going to be saying somebody else's words. I don't think I'd have the stamina, skill or ability to write a novel, but I'd love to write short stories and poetry, because those are my two passions.

I've always had, like, from the age of about 11, I've had such an intolerance for bad behaviour of actors that I don't think I was ever going to be that person.

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.

Working hard is important. But there is something that matters even more, believing in yourself.
