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.

Up there on the screen, we can all fly. But down here on earth, we need to be each others wings.

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.

People ask, "Do you enjoy acting?" But you only have those specific few hours to do a scene, and then you drive home and wait for six months to find out how it went. You can't go back and put in a new idea. Filming is about continuing to be alert and to think, and I find it quite exhausting. Certainly I would say that fear is a part of that.

The fear of messing up is what makes you work harder!

As an actor there's a lot of scrutiny and, even when you've had success, it becomes about sustaining that success. A friend of mine described it as a peakless mountain. Even for Robert De Niro there's Al Pacino and for Pacino there's De Niro.

I go to the theater two or three times a week when I'm in London. Whereas I feel guilty going to the cinema in the middle of the afternoon.
