Continuity: When Akeem and Semmi get their apartment, the landlord says that the room has only one window facing a brick wall. But when Akeem is out on the fire escape, he yells out to a street, not a wall. And there are two windows.

Continuity: In the scene where Semmi and Akeem are cleaning the soap from the window of McDowells the amount of soap on the window constantly changes from less to more and back to less again. (Look at the very top of the window pane).
