Factual error: At the end of the movie, Pat is watching a news report about John Lennon's death, which is intercut with scenes of Darby making preparations for his fatal overdose. Darby died almost a whole day before Lennon's assassination.
Continuity mistake: During the September 4, 1977 show at the Masque, Darby cuts a line on his chest with broken glass. The shape and position of the cut changes between shots during and after the show.
