Hi D,
This was first shown last year in Toronto and is already available as a DVD in Norway! We (the UK) are probably the last people to see it!
It was written by Jon Savage; author of ‘England’s Dreaming’ and original designer of some of JDs tour posters, and involves the remaining original band members, Kevin Cummins, Peter Saville, Deborah Curtis, Paul Morley etc.
Said to be the 'definitive' Joy Division documentary...although I reckon there's at least 25,000,000 definitive Joy Division documentaries by now!
