Continuity mistake: The whole big prison bus escape scene revolves around Chris Tucker being handcuffed to the French guy, but when Frenchy's friend arrives in the bus he stands up and hugs him while the handcuff is shown completely unlocked from Tucker's hand. In the next shot and the entire next scene they are still handcuffed together.
Continuity mistake: During the scene in which Chris Tucker is in jail recounting his story to Faizon Love (about how the cops handled him when being arrested), in a shot showing the bodies and heads of Tucker and Love while they sit side by side on a bench, Love takes off his shirt and unzips his pants, exposing his orange underwear. A few moments later, another shot shows both men again, but this time, Love's pants are zipped up, no longer exposing the underwear.
Revealing mistake: When Franklin leaps out of the helicopter into the water, there is a shot from above that we see he is about to hit the water. To the left of him in the water you can see the water being split by a helicopter close to the water. The waves wouldn't have been created from the helicopter he just jumped out of because, a)The helicopter was too high up to make that sort of marking in the water and b)The waves are being made to the left of the helicopter. If it was the helicopter Franklin jumped from the markings on the water would have be directly below him or below the helicopter.
