* ActingForTwo: Eddie Murphy and Arsenio Hall.
* ActorAllusion:
** As King Jaffe Joffer, Creator/JamesEarlJones tells Cleo [=McDowell=] "Do not alert him [Akeem] to my presence. I will deal with him myself.", referencing two different lines as [[Franchise/StarWars Darth Vader]] in ''Film/TheEmpireStrikesBack'' and ''Film/ReturnOfTheJedi''.
** Also, cameos by Ralph Bellamy and Don Ameche as the Duke Brothers, who Eddie Murphy and Dan Aykroyd sent to the poorhouse in ''Film/TradingPlaces''. This film is also the ''source'' of a later allusion: Creator/SamuelLJackson played an armed robber holding up a cheap diner in this movie, and [[Film/PulpFiction several years later]] would ''foil'' a pair of armed robbers holding up a cheap diner.
* DawsonCasting: 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.
* HeyItsThatGuy:
** [[Film/BeverlyHillsCop Axel Foley]]/[[WesternAnimation/{{Shrek}} Donkey]] is the Prince Akeem, [[Franchise/StarWars Darth Vader]] is his Dad the king and late-night talkshow host Arsenio Hall his sidekick. Plus, Creator/SamuelLJackson plays an armed robber who holds up the restaurant Akeem is working at.
** And [[{{Roots}} Old Kunta Kinte]] owns said restaurant.
** Cuba Gooding, Jr. plays a guy getting his hair cut.
** Creator/JamesEarlJones, who would go on to voice Mufasa in ''Disney/TheLionKing'', arrives in New York wearing a lion skin.
** And the queen, played by Madge Sinclair, would also be Sarabi, Mufasa's queen.
** [[LifeWithLouie Louie]] is Akeem's co-worker.
** [[{{ER}} Dr. Peter Benton]] is Lisa's [[RomanticFalseLead starter boyfriend]].
* TalkingToHimself: Hall and Murphy play three of the four characters in the barbershop; one of whom is an AlterKocker.
* TechnologyMarchesOn: 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.
