Factual error: When Judith wakes up chained to the engine block she notices the Sony camera on a pole. The guys are presumably watching her through that camera. The problem is that there are no cables running from that camera to provide the video feed to the TV. Sony cameras always have the video output connections on the front right hand side. There are no cables attached to this camera.
Factual error: At the beginning of the film when Wayne's mother has her water break at the 1972 Hot August Night concert, you see Neil singing in a silver spangly 90's shirt. As all true fans know (and the album cover shows during one of the house scenes), Neil was in a denim jacket and jeans with a lot more wild hair.
