Here's a breakdown:
* New York City: Much of the film's urban setting, including the streets of Queens and the fictional "Zamunda" palace, was filmed in New York City.
* Los Angeles: Scenes involving McDowell's, the fast-food restaurant, were filmed in Los Angeles.
* Queens, New York: The exteriors of the Queens home where Akeem lives with his friends was filmed in Queens.
The film cleverly used sets and locations to create the illusion of a vibrant and bustling African country, while still grounding the story in a familiar American setting.
