Revealing: During the dancing scene, Jamal shows the percussionist how to use the tambourine first, then tells him to start drumming, so he puts the tambourine down. However when he cues in the guitar, the tambourine starts to play again with the drums and guitar. A few shots later, with the tambourine still playing in the background, you can see the percussionist's tambourine sitting on the table next to him where he had left it.
Factual error: Towards the end, when the medics are reviving Martin Lawrence, they are using a defibrillator. You can hear the sounds of the defibrillator charging and then discharging. They then show Martin Lawrence wake up, but he is fully dressed. In order for a defibrillator to work, it must come in contact with the skin. I doubt they had enough time to redress him after using it on him.
Plot hole: The legend of the black knight (in this film) is that he can breathe dragon's fire. Jamal somehow rigs up his aerosol spray-can inside his helmet to shoot out the flames. However, there are three problems with this: one, how did it fit in the helmet? Two, how did he activate the spraying mechanism without his hands? And three, how did he even ignite the spray?
