Other mistake: During the scene where Markus and Jackie are making love for the first time, as she is straddled on top of him, you can see that she that she is wearing knickers (panties).
Continuity mistake: At one point in the film Markus watches a NBA game between Bulls and Knicks in the 1991 NBA playoffs. In another scene while Markus is at the gym his friend is wearing a 1992 dream team shirt.
Visible crew/equipment: After the office party Bony T (Chris Rock) and Marcus have a conversation about how people are betting on how long it will take for Marcus to sleep with Jackie. After Marcus walks off Bony says "Not you Marcus, you the man!" Pay attention, as he pushes off with the mail cart he bumps into what seems to be the camera. (00:33:05)
