Factual error: The movie and events take place in 1958. However, two Fender amplifiers that are used by the band, "Johnny Casino and The Gamblers" are "Silverface" models that were only manufactured between 1967 and 1981.
Visible crew/equipment: As the Tin Man gets to the end of his song, he's dancing in front of three mirrors. If you look past him as he's centered in the middle mirror, you can see the camera lens looking out of the canvas at him.
Continuity mistake: Towards the end of the movie, after FVB (Aerosmith) sings, and Strawberry Fields (Sandy Farina) falls off of the platform. She lands on her front, but when Billy Shears (Peter Frampton) runs down the stairs to her, she is on her back.
Factual error: In the opening, they are playing 'Life in the Fast Lane' by the Eagles, and they do a closeup of the studio turntable playing the last song on an album, but 'Life in the Fast Lane' is the second song on 'Hotel California' - not the last. (00:04:24)
