In the film Tony Wilson is seen at the funeral of Ian Curtis however in real life he could not attend the funeral as he was given the task of looking after Annik Honore, Ian's lover from Belgium, so that she would not attend the funeral and cause upset. She had come to see Ian before he flew with the band to America for the tour.
Ian Curtis' first epileptic seizure did not occur onstage, as in the film, but in the car on the way home from a Joy Division gig. It is also shown as occurring after the band composed 'She's Lost Control', a song that reflected upon Curtis' disease.
The film shows Ian Curtis having hanged himself while watching the Werner Herzog film "Stroszek". He actually hanged himself after he finished watching the film, and while listening to the Iggy Pop album "The Idiot".
The Haçienda's last night of operation wasn't a rave night as seen in the film. It was actually a performance by the English space rock band Spiritualized. The building was used for two parties after the club officially closed.
At the Sex Pistols concert, Tony Wilson identifies one of the groups there as "Stiff Kittens, later Warsaw, later Joy Division, and finally New Order". The band never officially went by the name Stiff Kittens; they did allow it to be used on a poster for a show because they didn't have any other name they could use, but the first official name for that particular band was Warsaw.
