Plot hole: In the scene when Lisa and Akim are walking up to Akim's door (when Semi is sitting in the hot tub after fixing up their room), they are carrying groceries for Akim to cook Lisa dinner, however when Akim walks into the room (and every shot from inside the room) there is no kitchen for him to cook.
Visible crew/equipment: You can see bits of the camera crew reflecting on the carriages, when the metro-train leaves the station after Akeem has gotten out after Lisa refused to marry him (near the end of the film).
Continuity mistake: When Lisa moves to a different train carriage near the end, she opens two doors. She tries to slam the second door as Akeem is following her, but it bounces back and remains completely open. In the next shot, however, the door is completely closed, forcing Akeem to open it.Man Athan
