Revealing mistake: Watch the background fighters during the club scene; there are many occasions where you can see the actors are just waiting to get hit or fall down, most notably when the little kid is fighting the guy in the camouflage. A "fighter" up on stage is standing there with his arms up as a kid winds up a kick.
Continuity mistake: When Leroy is fighting Goliath in the club, the bald headed guy changes between lying face-up and face-down in almost every shot.
Continuity mistake: When Leroy is body slammed by Goliath in the dance club, he is picked up with his head to the lower left and his feet to the upper right. When Leroy lands, his head is on the upper right and his feet are lower left.
Continuity mistake: In the scene before the Shogun enters the movie theatre his crew enters first and two women line up on the right side of the doorway and the third on the left. In the shot as the Shogun begins to speak the same two women are now lined up on the left side with the third.
Other mistake: The film uses the same footage of the club fight whenever the camera is looking down to the floor. This can be proven by looking at the top right corner of the scene and seeing Johnny fight the same three guys with the exact same movements.
Revealing mistake: The fire escape is already lowered before the boys begin to walk down it, but it starts to lift up before the last boy steps off; someone must have been holding it down for the boys to descend, then let it go to get out of shot, thus allowing it to raise up.
Visible crew/equipment: As Richie and his friends climb down the fire escape, the camera and its operator can be seen in the window behind them.
Continuity mistake: When the three guys are dancing outside the cookie factory, a lady in a white jacket and sunglasses walks past them and stops to watch. When the guys end their performance, a wide shot of the crowd reveals she is not there, but she is again in a close-up as everyone laughs at Leroy.
Continuity mistake: After Leroy punches Sho'nuff in the stomach, the camera shows there is open space behind him but in the next shot Sho'nuff kicks him through a wall.
Continuity mistake: When Rock gags Laura, the handkerchief is hanging down from her mouth as he ties it off, in the next shot it is neatly folded.
