I saw this movie Berlin Calling, 2008 about a german DJ, I guess he's fictional, not a biography. Although I had a really bad opinion about electronic music in Germany, I have to say I liked the soundtrack a lot. I'm listening to Paul Kalkbrenner since then, on&on. I gave it a 7 on imdb, but it may deserved an 8.
Berlin electronic music composer Martin (Paul Kalkbrenner), known as DJ Ickarus, is touring with his manager and girlfriend Mathilde (Rita Lengyel) from club to club around the globe and is about to release their biggest album to date.
