Sometimes when you're making a film and something happens during a scene that you've just thought of, it can be missed if the wrong lens is on or if you're shooting in the wrong direction but this [performance capture] doesn't miss a thing. So, you might do something that's genius - very rarely, admittedly - but it doesn't miss it.

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 wouldn't change a thing in my life, even if I could. What you go through makes you who you are and that's fine.

I think I became an actor because I couldn't sing.

You've always got to have an imagination in the game we're in but it explodes on this. You get to try the costumes on before you start and feel the weight of them, which is great. But then you're opposite some of the greatest actors in the world and away you go. You find your imagination takes over without you really even thinking about it.

Well, for me, my favourite 'Indiana Jones' is 'The Last Crusade,' because you get tears in your eyes when you see the old guard standing at the end, so that's my favourite one.

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.
