I can't go to war with paparazzi.

Every movie I get involved with I get involved in as big a level as I possibly can, but this has been a very much more personal journey for me, so bringing it here tonight there's a sense of relief, there's a sense of just amazement that got here... because it's been a struggle. But this is a good way to launch it and there couldn't be a better way of celebrating this movie than bringing it to the West End.

I never had any boyhood ambitions.

There is also a distinct possibility that there are other actors ? whose names have not leaked to the press ? who may stand just as good a chance of landing the part.

Literally, the piece at the end is where the universe is cracked apart, it's a big moment. Basically, they, the filmmakers, have directed the story earlier in the book. It happens, it's called adapting a book, you have to make decisions about things. It's not unusual having to cut out scenes.

There is, come to think of it, a kind of Judi Dench quality to McCain.

Obviously, when I came to do the movie I knew that I was going to have to take my clothes off so I might have worked a little bit harder to keep myself fit. But I think that's the irony of it - you see all these fit and healthy people, and I'm not making any comments on it, but everybody deep down is a f**k up somewhere.
