Continuity mistake: Toward the end of the film Ruby says goodbye to her family and gets in the car to head to college. The car pulls away from her home and drives for about 5 seconds when Ruby yells "stop the car". She exits the car which is positioned nearly exactly where it was when they started on the families' property.
Continuity mistake: Walter takes part in a trial performance to join Erika's piano master class. When he opens the door to the concert hall his collar button is open, but when the camera angle changes and the door is seen from inside the shirt is closed. (00:28:55)
Continuity mistake: In the room when DJay first plays his keyboard, the dirt pattern on the door behind him changes drastically when the scene changes.
Audio problem: Near the end of the film, when the Commodores finally go on stage with their equipment, Bobby Speed announces them from inside the control booth. But the movement of his mouth does not match the audio (you have to look at his reflection in the glass wall).
Continuity mistake: When Bette Midler is in the phone booth toward the end of the film, calling home and crying, she empties out her purse on the little shelf. A huge roll of money is prominently placed amongst the coins and other items. From shot to shot it can be seen sitting upright and then on its side.
Continuity mistake: When they are in the bar in Broken Hill, Old Shirl comes over and slaps her right hand down on Bernadette's. Then, in the next camera shot, it's her left hand.
Audio problem: In the close-up, as Jack is whistling "Toot-Toot-Tootsie," it doesn't match up with his mouth.
Continuity mistake: When evil Swan hands the contract to the Swan who's about to kill himself, Swan grabs the contract out of E.S hands, yet in the next shot, E.S is still holding it.
Continuity mistake: In the scene where Jack Nicholson finds the piano on the back of the moving truck, he uncovers it and tosses the tarp on the side of the truck. Over the next few shots, the tarp disappears and then reappears draped over the side of the truck. As well, the shots of Billy Green Bush taken from outside the vehicle show his hands gesticulating wildly, while the shots from inside the vehicle, from over his right shoulder, show his right hand calmly positioned on the upper right part of the wheel. This scene also contains a magically appearing chair. When Jack first finds the piano, he has to lean over to play, but a few shots later, he is seated comfortably on a straight-backed kitchen chair. (00:19:10)
Continuity mistake: At the beginning, when Benny G is sitting in his car listening to the remake of his song "I Cry" on the radio, in the exterior shot of the car there is a massive amount of water on the window. But, in the interior shot, there is not as much water on the window anymore, and there was no time between shots to put the windscreen wipers on.
Factual error: One of the operetta excerpts shown in the movie is the humorous song "This Helmet I Suppose," during which Princess Ida's three brothers are supposed to remove their armor piece by piece, finding it heavy, hot and awkward. Partly as a result of this, the three are soon afterwards quickly and easily defeated in combat. In the film, however, only Arac, the brother singing the verses (played by Richard Temple (played by Timothy Spall)), removes his armor. The others simply stand still. (This might have made the battle scene end differently if it was shown on screen!)
Other mistake: When a Japanese newspaper is shown publicizing Jackie's performance, the headline above the photo actually reported that the Japanese budget had been approved by parliament.
Audio problem: Much of Karen's drumming is not in sync with the drum sounds.
Factual error: When testing the new phone installation, the engineer only dialled the number, and not the area code, as you have to do on a mobile phone.
Continuity mistake: When Tony is trying out for the second show, he is shown wearing number 46. There is one shot of him wearing number 40, which was his number for the first tryout.
Continuity mistake: When François starts talking to Coco in the cafe, the donut on her plate and items on the bar next to her keep moving between shots.
Continuity mistake: People are often shown listening to the radio at completely different times of day to the times shown on the boat.
Continuity mistake: Tris tries to seduce Nick at the river by dancing in front of the headlights of his car. He decides to abandon her, and backs the car away. When he cranks the steering wheel clockwise and points the car up river to leave, the camera cuts to a shot of Tris standing by the river, but the headlights are still on her.
Continuity mistake: In the Fish and Chip van, the guy with the pony tail says, "I'm going to fart." The next few shots have his head alternating in different positions even though there was no time for him to move.
Other mistake: In the scene when Hector Lavoe and his wife (Mark Anthony and JLo) are walking down the street in New York, on the right hand of the screen you will see a man taking a picture with his cell phone. The scene is supposed to be based in the 70's.
