For me, 'The Crystal Skull' was something I'd never done before, and I loved every minute of it. Working with Harrison Ford as well - he's a cowboy from Montana, the most unassuming man you'll ever work with, fabulous guy, and I loved it.

I pile on the weight when I work. All that location catering's not good for the love handles. I lose a bit when I'm not working, but I love my food and the occasional snifter.

I'm lucky enough to have a kid with me who is actually really intellectually up with what's going on in the world and actually puts his money where his mouth is and goes and does something about it; he goes and talks about it. It livens you up a bit and it brings you into the 21st Century.

Almost all politicians drive me insane. These people are supposed to be looking after us. What I hate is that we don't speak up enough as a nation and take on the government.

We sometimes get lost in a bubble... when you get to a certain age you're always thinking about the old days and how it wasn't like that then. Well, yeah, that's great and it's very nostalgic and all that, but actually the world has moved on.

Sometimes you also work with people who don't explain or express to you what they're actually looking for from the shot but you haven't got that problem with this because whatever you're going to do, whether it's good or bad, will get picked up. So, in that way I guess it's pure cinema.

But then when you go through the process of making the film and you sit in the cinema two years later and your jaw hits the floor, it's quite sad in a way because you're looking at yourself - facially anyway - and see the way you looked when you were 20.
