Factual error: When Peter has his KISS trivia game with Dave the nudist, he asks what the ad read that brought Peter Criss to KISS, and they both answer in unison: "Drummer willing to do anything to make it". In fact, the ad read: "Drummer with 15 years' experience willing to do anything to make it". As the original ad is referenced and shown in several biographies on KISS, as well as the "KISS: eXposed" video, it's not something these two trivia experts would have missed.
Continuity mistake: When Gene Simmons points the microphone at Lois, she is surrounded by people with Kiss make-up on. In the next shot, when she says "Is that it?", she is surrounded by a different group of people, one of whom is not wearing make-up.
