* 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: Murphy is definitely older than 21.
* HeyItsThatGuy:

** 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.

** [[LifeWithLouie Louie]] is Akeem's co-worker.
** [[{{ER}} Dr. Peter Benton]] is Lisa's [[RomanticFalseLead starter boyfriend]].
