"Next is a documentary called Night and Fog by Alain Resnais, which is a story of then and now, of concentration camps. That had a major influence on me, again, for the poetry, if you can call it that, of the documentary, but also the way he used time, the way he used two time zones, two sets of material, to make his point, and to give the film, which obviously had some astounding, alarming images in it, but without a lot of babble, of explanation, by contrasting what it once was and what it is now. It was very moving to me, and I think that was inspirational, again, in the [Up] films I did with these children, which I’m still doing. But I could see how you could time travel in documentary, and it makes both sets of material more powerful. Of course, the film is incredibly powerful anyway. But nonetheless, he’d found a style of doing it, a way of doing it… It’s just, the power of those images, without endless babble, was, to me, a very strong lesson."
