I became obsessed with the true stuff, and that led to shaping 'The Way Back' screenplay somewhat toward a minimalist style, to avoid free-hanging moments, and to hold the music back, so it would never lead you to an emotion, and to try to make the emotions as real as I could.

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.

It's spiritual, a man that has a past and regrets, but you can as a director take a shot, and there's something in the eyes and the face, you just can't fake it, you can't teach it, and I think Ed Harris has that quality.

Silent films were, I think, more different than we know to sound films. We think of it as simply that we added dialogue and in actual fact I think it was an entirely different art form.

In terms of how I work with actors, having worked so heavily on the script I have a very clear idea of the characters; they are reasonably well illustrated in the script. If you cast it right, to a great degree you can hand it over to the actor and I just make suggestions. I'm not the kind of director who needs or wants to get into too much finessing. Ideally, when you hit the set, you have this conversation, like, 'eh, what did you think?' 'I don't know, what did you think?' 'Why don't we just try it again, make a few physical changes.'

I always thought the editor should cut the film and so I'll come in and look at the movie. Just because that's the only way I can really see the ideas of the editor, it's really working together. Yes it's a hierarchy, yes I'm the boss, but I like to see and to think about the idea, and it's about us asking, 'do we have to say that?' and, 'how do we make it there?' So it's advising the editor, it's very give and take, it's very free, but in the end, it's wonderful once you get through the first couple of cuts.

I had always been wary of doing any autobiographical movies, truly feeling at home with fiction.
