Growing up, I spent a lot of time on film sets all over the world.

You know, the great thing about acting or, indeed, filmmaking in general, is that we're all given a reason to do research. You kind of have to, really, if you want to know what you're doing, but it opens up this whole new understanding.

I had no ambition to become an actor at all.

As an actor, it's hard to direct because, suddenly, you're not around. The thing which I hate about directing is the waiting game, but you've really got to wait it out and be resilient and keep it going and keep everybody motivated.
