There's always been a relationship between the film world and fashion.

When you're doing a film that has so many effects, you do a lot of it on green screen, and you can't see what that world is.

My favorite film is probably the finale - 'Deathly Hallows: Part 2'.

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'm quite ignorant about fashion and I'm colourblind, so it's all a tad tricky. My only knowledge of that world comes through Christopher Bailey, whom I first met in 2008 when I did a campaign for Burberry that featured musicians, artists, actors and sportsmen.

There is a certain amount of commerce in the film industry in as much as you have value, and for a moment, your value goes up, then it all disappears again.
