You might want to check out the independent film released last year "Control", it depicts Ian Curtis's life in and out of the band. I really enjoyed it, great acting and soundtrack (naturally), it was filmed in black and white, which complements Ian's story a lot better than in color. If you like Joy Division, you must check it out, even if you don't like them it's still a good and dramatic (but not melodramatic) film.
I bought the 2-disk reissue CDs by them recently. I was into them a few years back, but it seems they have been gaining a lot of popularity (reissues, the film I mentioned, etc.), plus I had a post-punk phase a few months ago, so I had to finally buy Unknown Pleasures and Closer. The live discs are pretty good, and the studio albums sounds nicely remastered. I have to say I prefer Closer, I find it a lot more varied, interesting, and emotional.
