Other mistake: In the intro to the Pastoral Symphony, the narrator identifies the deity who cloaks the world with Night to be Morpheus, who is the Greek god of sleep and dreams. However, the character in the animation is fairly obviously female, with long hair, eye shadow, and lipstick. My theory is that the character was intended by the art team to be Nyx, the Greek goddess of Night. Night would be a more likely candidate to be making it nighttime across the world, while Morpheus would be more likely to put people to sleep or send them dreams.
Suggested correction: Without further evidence/proof, this theory remains just that. A theory.
Other mistake: In the final scene both at the start when Fletcher is walking on stage and in a shot during "Caravan," just after Andrew mouths FU, when Fletcher puts a hand under his jacket the shot goes forward and then immediately shows the same footage in reverse. (01:27:55 - 01:32:45)
Other mistake: In the scene where Paolo leaves the stage after everyone discovers that he can't sing, his bodyguard Serge stops him and Paolo suddenly loses his Italian accent. Paolo sounds very American when he says "You work for me, Serge."

Other mistake: When Kevin and Perry go home to find the postman at the front door, the postman asks Kevin to sign for a letter (his father's). If you look closely at the address on the postman's sheet it does not match the address on the letter. You need to be quick and look closely.

Other mistake: Carolyn Stilton shoots Blondie O'Hara in the head and is lying dead over her dead husband. Just before the final scene starts she begins to open her eye.
Other mistake: When Apollonia is smacked in the face by the Kid after announcing she's joining Morris's group, she falls into a dresser and knocks all the magazines off the top of the dresser on to the floor. When the same scene is replayed during the 'When Doves Cry' sequence, the magazines don't fall to the floor.
Other mistake: During one of the recording studio scenes, there's a short segment that shows a bunch of VU (audio level) meters close up. The very first meter in that sequence is not a VU meter. Its from of an old HF (High Frequency) Amateur Radio transceiver; The scale is marked for RF, SWR, and ALC. I'm suspecting that someone involved with the post production editing is a Ham.
Other mistake: Watch when two bodyguards shove Mel and Val towards the car at the end of the movie- one of the bodyguards steps on Val's tail and nearly trips.

Other mistake: On the first day of the Big Bounce, during the dancing, a white towel-like object is dropped on the floor and in the next shot it is gone.
Other mistake: When Paul is making the DVD, there's a record of Terri performing a song she wrote(One more mile to Jericho). At the very end, outside the school the kids start play some music together with Terri singing. That's supposed to be some random thing like it was before, but actually they play and sing Terri's own song. How come?
