New Daniel Radcliffe interview

Have you gone back and watched the first two films at all?

I haven’t seen the first one in a few years. I don’t want to watch it. I won’t go back while I’m doing the fourth one. Actually, I was flicking through the channels one day and I saw a bit of the first film and I genuinely thought there was something wrong with the sound because our voices were so high. It sounded like I was on helium, it was bizarre, and I genuinely thought there was something wrong with it.

I will probably watch them one day for fun — although I’m not sure how much fun it would be because I’m really self-critical. I don’t like watching myself at all but luckily I can detach myself from it. 'I'll see it again one day but I'm a big self-critic'

Do you have any plans for your birthday? (July 23)

I’ll most likely be filming but what normally happens is you get a cake from everyone on set and the great thing about filming when you have your birthday is that there are so many people there and you get loads of presents. You just have a little party on set.

Luckily all the people on set are really cool so I’ll have a good time. There’s one guy Will, my dresser, who’s become like my best friend.

Is Emma a lot more worried about what’s she’s wearing now, things like that?

Well Emma’s always been like that. Not in a bad way at all but she’s very style-conscious. I think what we wore in the early films contributed. You know, ‘I don’t look very cool in the films, so I have to try and look cool out of them’. Emma’s great. She’s a really nice girl.
