Joy Division were great, after Ian Curtis left, New Order never reached that intensity anymore. You should be able to find Anton Corbijns film Control (2007) on dvd (at least for region 2).
I recall, I went through agonizing months of obligatory military service back in 1980 and Dark Wave music perfectly reflected my state of mind, so I liked to play Joy Division on cassette, now and then. Another occasion for normal people to suspect Id gone bonkers =8^o (oh well, Id heard that before in school and college when listening to the likes of Beefheart, Gong or Henry Cow.)
