Continuity mistake: Though Fausto Zoppi and Jean-Claude Moleno are to have contributed to the 'World's Most Fabulous Meal' for the Queen, neither of them ever shows up in the kitchen during the preparation of the dinner. They don't even appear until much later in the film.
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.
Continuity mistake: It is easy to see Ace Frehley was wearing black leather shirt/pants at the beginning of the film. When they are fighting the robots next to the Rollercoaster, his suit is white leather.
Continuity mistake: In the final scene when Paul gets the lacrosse team to get off the coach, when the camera is inside the coach two girls are off first, followed by the lady teacher.
