* ActingForTwo: Creator/EddieMurphy and Creator/ArsenioHall. Technically, both are Acting For Four.
* 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 Creator/EddieMurphy and Creator/DanAykroyd 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. Creator/EddieMurphy, who played the prince, was actually 27 at the time.
* DeletedScene: Cuba Gooding, Jr. shot a scene in which his character (Boy Getting Haircut) tells Clarence that he does not have money to pay for his haircut. Clarence responds by cutting a big chunk out of the boy's hair. But to Gooding's disappointment, the scene was deleted.
* HostilityOnTheSet: While Creator/EddieMurphy and Creator/JohnLandis worked together well on ''Film/TradingPlaces'', here they had a clash of personalities, though they did work together again on ''Film/BeverlyHillsCopIII''. Landis recalled:
-->The guy on ''Trading Places'' was young and full of energy and curious and funny and fresh and great. The guy on ''Coming to America'' was the pig of the world... But I still think he's wonderful in the movie."
** Murphy recalled:
-->We had a tussling confrontation…We didn't come to blows. Personalities didn't mesh. I grabbed him, and he thought I was playing. So he tried to grab my balls and I pushed him away. But I wasn't kidding. He was doing some silly shit that made me mad. He directed me in ''Trading Places'' when I was just starting out as a kid, but he was still treating me like a kid five years later during ''Coming to America''. And I hired him to direct the movie! I was gonna direct ''Coming to America'' myself, but I knew that Landis had just done three fucked-up pictures in a row and that his career was hanging by a thread after [[Film/TwilightZoneTheMovie the Twilight Zone]] trial. I figured the guy was nice to me when I did ''Trading Places'', so I'd give him a shot… I was going out of my way to help this guy, and he fucked me over. Now he's got a hit picture on his resumé, a movie that made over $200 million, as opposed to him coming off a couple of fucked-up movies – which is where I'd rather see him be right now (laughs).
* MissingTrailerScene: There was a scene featured in the theatrical trailer that was cut from the final film. In it, Cleo McDowell, Akeem, and Semmi walk into Cleo's office, where he asks if either of them have had any fast food work experience. Semmi responds "Certainly not!" Akeem then nudges Semmi, and tells Cleo that this is their first job in the United States.
* RecycledTheSeries: A television pilot of a weekly sitcom version of the film was produced for CBS, following the film's success, starring Tommy Davidson as Prince Tariq, and Paul Bates reprising his role as Oha. The pilot went unsold, but was televised on July 4, 1989 as part of the Creator/{{CBS}} ''Summer Playhouse'' pilot anthology series.
* 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.
* UnintentionalPeriodPiece: This film dates itself to the late 1980s with its depiction of Pre-Giuliani NYC, its fashion, its soundtrack, describing UsefulNotes/MikeTyson as a "new boy" in boxing, and the presen
* WhatCouldHaveBeen: Creator/SidneyPoitier was considered for King Jaffe Joffer.
* WorkingTitle: ''The Quest''.
