"The locations I've used were old disused power stations around Philadelphia and Baltimore. Nuclear plants, factories, power stations: "cathedrals of technological progress." I've always had a problem with the belief that technology was going to solve all of our problems; so I'm drawn to shooting in those places, particularly for this film, which is about decay and about nostalgia. These great spaces were considered to be providing the solution to all of our problems, yet now they're just wasted, lying there, rotting. And that seemed very much what a lot of the film was about. About putting your faith in the wrong things."
