Also, cameos by Ralph Bellamy and Don Ameche as the Duke Brothers, who Eddie Murphy and Dan Aykroyd sent to the poorhouse in Trading Places. This film is also the source of a later allusion: Samuel L. Jackson played an armed robber holding up a cheap diner in this movie, and several years later would foil a pair of armed robbers holding up a cheap diner.
Dawson Casting: The movie opens on Prince Akeem's 21st birthday. Eddie Murphy, who played the prince, does not look 21, which makes sense considering he was 37 at the time.
Axel Foley/Donkey is the Prince Akeem, Darth Vader is his Dad the king and late-night talkshow host Arsenio Hall his sidekick. Plus, Samuel L. Jackson plays an armed robber who holds up the restaurant Akeem is working at.
Technology Marches On: If mobile phones were more widespread at the time, Semmi might have texted Akeem that his parents, the King and Queen, are in New York, and he's gone with them to the Waldorf Astoria.
