Most actors hate watching their own films because all you can see is the glaring mistakes, your own tricks and ticks.

It's the weird thing Eton does - you're at school next to lords and earls and, in my case, Prince William, so you end up being used to dealing with those sorts of people.

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.

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.

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

I'm as voyeuristic and intrigued as the next person as to how celebrities live.
