Ian Curtis sits at home, watching the Werner Herzog film "Stroszek", opening a bottle of whiskey during a scene, where the mobile home of Stroszeks protagonists is auctioned off. In the next scene, presumably some time later, we see that Curtis is visibly intoxicated and that the bottle is almost empty. However, in "Stroszek" barely two minutes have gone by.
On the contract signed in Tony's blood, drummer Stephen Morris' name is spelled Steven. (The band mocks Tony's lightheadedness from the blood loss by falsely telling him that "Morris" needs to have a second "s" added, but no mention is made of the misspelling of his first name.)
Joy Division is shown performing "Transmission" on Tony Wilson's television show in September 1978, but in reality, they performed "Shadowplay". The performance that is represented in this scene actually took place a year later in September 1979 on the BBC2 program "Something Else", when they performed "Transmission" (a performance which was used as the music video for the song) and "She's Lost Control".
In Ian's bathroom medicine cabinet is a bottle of Tigabine an anti-epileptic not available till the 1990's.
In a song performance scene the guitarist is using Marshall Speaker Cabinets (model 1960A and 1960B). The speaker cabinets were not introduced until several years after Ian's death.
When Ian is recording the vocals for "Isolation," he appears to be using a modern Shure KSM27 studio condenser microphone.
