Eddie Redmayne

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.

Listen, acting is not surgery, it's entertainment. You're doing something to hopefully move people, to make them laugh, to transport them. But actors are vulnerable, and the reason we're vulnerable is that we're always trying to recreate human behaviour.

Two years ago, I shot 'Pillars of the Earth' in Budapest - it was a big part, but I had a lot of time to sit around and visit cafes.

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.

I have this horrific thing where I'm really bad with names and faces. I have an appalling memory. Someone will come up to me in the street and go, 'Eddie!', and I'll try and give myself time by going into overdrive, 'Hey, hi! Nice to see you!' and start a whole conversation because I can't distinguish between who I know and who I don't.

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 first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.

Everything about filmmaking is incredibly weird, and there's nothing natural about watching yourself on the big screen or hearing your voice. It's that same thing that you feel when you watch yourself on a video camera and you hate the sound of your voice - it's that times 800.

I've never been someone that was sort of blessed with an innate talent of just being able to do things. I had to work at it and learn from mistakes.

There's something scary about acting always, because basically you do all this work in a vacuum, and then suddenly there's a lot of money spent making a film, and there's suddenly a camera here, going, 'Right? What are you gonna do?'

What is important is for me to do my best work on camera. The camera is inches away from you and sees every micromovement of every muscle of your eye. And if you're not relaxed, the camera sees it.

On so many levels, acting in film and TV is so much the sum of its parts, and somewhere in there, there's an alchemical thing that makes something happen or not - that makes something connect or not. Now, of course you want to make work that people see, but the enjoyment I get out of acting is playing characters.
