I think that London is very much like that. I find there's humour in the air and people are interesting. And I think that it's a place which is constantly surprising. The worst thing about it? I think it can be smug and aggressive.

Because I am an Englishman I spent most of my life in a state of embarrassment.

My primary instinct as an actor is not the big transformation. It's thrilling if a performer can do that well, but that's not me. Often with actors, it's a case of witnessing a big party piece but wondering afterwards, where's the substance?

I often think it can often be very difficult for comedians to revisit the same gag. I think Russell's a bit more than a comedian.

It's whether they have a vision and whether they're able to communicate it. The best director is just someone who gets over-excited about doing it - they don't even have to know much about camera or acting.

The great thing about dealing with people about whom we have historical resources, is that if the writing needs work, there's everywhere to go to enrich it.

I haven't had to struggle very much. I haven't paid my dues. I think I have been lucky.
