Corrected entry: When Kiss is playing live they are using wireless guitars, but the film takes place in 1978 when they were still plugging directly into the amps with cords.
Corrected entry: in the scene where they are driving down the road with Christine in the back after beating up the Guidos, she says something like, "I wouldn't be surprised if Kiss made a disco song," and the other guys all just laugh and say that'll never happen. What's funny here is Kiss made the song "I Was Made for Lovin' You," which is a disco rock kind of song as a way to show how easy it would be to make a disco song.
Corrected entry: When they are all running out of the church school they don't have the priest's pizza, but in the car, they do.
Corrected entry: There are supposed to be four guys in the Volvo on the way to Detroit, but in one shot while they are debating whether or not to pick up Christine there is only one person in the car.
Corrected entry: In the beginning when the boys are playing, it is actually them playing and not a recording.
Corrected entry: When the boys are driving the Volvo to Detroit the drivers' side window is open then every other shot it is closed. It is open and closed about six times in 30 seconds.
Corrected entry: In the convenience store scene, Trip is leafing through a copy of the Marvel Comics KISS Super Special comic that he picked up off a comic rack. This comic came out in summer 1976. By the time the movie is set, (1978) there would be no way a copy would be on a news-stand for a few reasons: The print run sold out, so no copies would have been left over. By this time, all copies were safely tucked away in the hands of collectors. No retailer keeps old issues on the news-stand, even if 'a' were not true. This comic was magazine sized and was merchandised on magazine racks, not comic racks.
