"When I became a film academic in the 1980s, I was allocated a class through which I discovered silent (or rather non-sync-sound) films. I had never appreciated the extraordinary beauty of this cinema and, most of all, I loved films of the very late twenties, made on the cusp of the transition—for instance, Josef von Sternberg’s Underworld and The Docks of New York. People on Sunday is an amazing film document of Berlin just before the Nazis came to power, and is also a “young modern woman” film."

"Me and Rick were living in a terraced house in Splott in Cardiff, near Tiger Bay. That’s where we formed our first band, Freur. We were making dub electronics and listening to dub reggae and Kraftwerk’s Computer World and Bowie’s Low. What blew us away was Brian’s (Eno) analogue electronic sound – that kind of degraded sound that he was making – and the fact that this great icon, a hugely famous singer and frontman, had chosen not to sing for half an album. What guts and courage that seemed to take. Years later you read that it ended up like that because he wasn’t around and that Brian experimented in his absence. But it takes great foresight and courage for David to come back and hear that and say, "yep, that’s the album." And not to think that because he’s a singer he has to blast away over the top of it. So that became a part of the blueprint for Underworld – that the singer doesn’t have to be the dominant force. He can play a supporting role. That Berlin period – the three Bowie albums and the Iggy Pop record – deepened the mythology of what I love about Berlin. The idea of going to a place and locking yourself away and making quite an extreme record in a different environment"

"In recent years, with financing so much harder to come by and the best television raising itself to the level of great filmmaking, I’ve been happily earning a living working in serialized cable dramas, while still trying to get my own films made. For me, Berlin Alexanderplatz was the grandfather of all the best of modern television, using the expanse of hours to dig ever deeper under the skin of characters, seducing us into caring for a dark antihero in spite of ourselves, and showing that television can be as visual and inventive and surreal as the best movies. I hope we get a Blu-ray version soon!"
