I'm not from a theatre background, I'm wary of rehearsals. But what I do like is hanging out together, on location.

I've done a number of things that get categories closed off in a way, so when I read 'The Long Walk' by Slavomir Rawicz and decided to do film, 'I thought, you know, this is going to be wonderful,' two and a half years, three years, whatever it was.

I think Ed Harris is a conscious screen actor, so I think it was strong, it was like he put everything together somehow in 'The Way Back'. He likes, I don't want to say the method approach, because that's not really necessarily his way of working, but it was easy to do because of the location. He'd go off by himself, and they would make things.

It doesn't take any imagination at all to feel awed

Casting is always critical but in this case, 'The Way Back', I was looking internationally to a degree for an interesting mix of gentlemen, Irish, Polish, Russian and American. Not many people had the qualifications, people who would play the game, particular to this industry. So I had to research amongst the cast. They had to be very very prepared as we had to start shooting as soon as we could, there wasn't any time to talk, and there would only be three or four takes.

I love stories and I don't like to repeat myself. And I look for new stuff, and as they say it gets harder.

I love a chance to shoot real locations, because in films in the earlier days before people traveled as much, it was exotic to see a film set in Switzerland, and that area has been taken over by CGI, mostly, and fantasy landscapes. It's unusual to see this much landscape, people say it's old fashioned. So what you're referring to is there was that period in the '50s and '60s when there were epics and you saw landscape.
