Factual error: At the end when the cops come after the fights. Ice Cube seems to be able to 1. tell the cops who to arrest even though the cops just arrived. And 2. Walk right out the front door of a house being raided by several cops with a the cash cylinder and no-one even seems to care. In reality everyone would have been arrested in handcuffs, questioned at the scene, and only released when or if it was determined they were not doing anything illegal.
Revealing mistake: When Deebo is getting attacked by Joker's dog, you can see protective padding on his arm.
Continuity mistake: When Day Day and Roach are taped together, the tape constantly changes. In one scene, the tape if very uniform in how it is wrapped around both of them. In the next scene, it is wrapped around them sloppily.
Continuity mistake: When Roach and Day Day are tied up and they start to spin around, the bandage on his arm has two spots of blood. When Roach is leaving Day Day's house with the dog, there is a line of blood.
Other mistake: Deebo's name is spelled with 2 e's, but throughout the movie the subtitles spell it with only 1 e.
Continuity mistake: Deebo kicks the door off Craig's dads truck yet when they drive away in the end it's back on.
Suggested correction: The door has been replaced, but it's crooked, implying that they put it back on and made it fit the best they could.
Continuity mistake: When Craig's dad buys his burrito before he is told about the bogus phone call, he also buys a small Pepsi which the guy hands to him with the burrito. He takes his burrito and a small Pepsi cup into the truck and drives off. Later, when he is trying to get off the freeway to go to the bathroom, there is a large Pepsi cup in the door holder.
Continuity mistake: During some scenes, Roach has a bandaid on his neck. Later in the same day, there's no band aid.
