I had never been to a fashion show before going to the Burberry show last month. It was an extraordinary spectacle. I was incredibly green and had no idea what an undertaking it is. I also have a new respect for models because they are so close to the front row and must be so self-conscious.

I think all actors have a similar deal. You want some people who understand. Although it looks great - and is great - there are also shoddy moments when you feel really rotten, and when it's going well, you're not allowed to complain.

I love the Potter films. I found them the most wonderful sort of escapism every year or two.

If you've loved something and then in some ways you become a part of it, you just don't want to be the one that screws it up!

They're such hierarchical things, film sets, they're sort of mini societies. Often they're incredibly political places.

Learning lines is hard for me because I have the attention span of a six year old. That's why being on planes all the time is so useful - I'm forced to learn out of boredom.

It can be a miserable profession, acting, because you always want what you can’t have.
