!!The Franchise in general:

* TheCharacterDiedWithHim: Trautman died off screen in the fourth movie because Creator/SylvesterStallone felt it wouldn't feel right replacing the late Richard Crenna. As he himself put it: "Trautman died the day my friend Richard died."
* DivorcedInstallment: For the ''Rambo'' Master System game, Sega's license was only applicable for the American version, so when it ended up being released in Japan and Europe, it was relabeled ''Ashura'' and ''Secret Commando'' respectively, with all use of Rambo imagery and theme music taken out.
* FakeRussian: Both Podovsky and Zaysen were played by an Englishman (Steven Berkoff) and a French (Marc de Jonge), respectively.
* HeyItsThatGuy:
** One of the deputies in FirstBlood went on to [[CSIMiami head a forensics team in Miami.]]
** Ericson in RFBII [[TheKarateKid runs a karate dojo in Recita and teaches his students "Mercy is for the weak"]].
** The hot blonde missionary in ''Rambo'' was a [[Series/{{Angel}} vampire]], the [[Series/{{Dexter}} wife of a serial killer]], and a [[{{Series/Defiance}} town mayor in a future semi-terraformed Earth]].
** Lewis, one of the mercs in ''Rambo'' was [[Series/RedDwarf "Nicey" Akerman]].
** [[Film/{{Octopussy}} Orlov]] was demoted to a lieutenant colonel and assumed a new identity.
* UnintentionalPeriodPiece: Parts II & III especially, due to their late ColdWar setting. Even the fourth movie is showing signs of this, with Myanmar slowly but surely opening up politically.
* WhatCouldHaveBeen: Sylvester Stallone was working on a script for a fifth Rambo movie, which would have featured the titular hero going into Mexico to rescue a teenage girl who had been kidnapped by the northern drug cartels. But after the success of ''Film/TheExpendables'' the project was scrapped so that Stallone could focus on the sequels for that franchise.
* In Japan, where ''{{Rambo}}'' was indeed very popular, the word "rambo" can be translated as "senseless violence"
** Likewise, in Finland, "Rambo" has become a generic word to describe a commando of any sort. So much so that many younger people are surprised to find out the word comes from the movies instead of the other way around.

!!Other trivia:
* In Taiwan, any knife with a serrated blade back has come to be called a "Rambo Knife".
* Rambo is in fact named after a US Postal Service worker, who also went on to cultivate a type of apple that now bears his name.
** His first name comes from the war song "When Johnny Comes Marching Home Again".
* Warhammer 40K has a homage to Rambo in the form of a special character for the Imperial Guard. His name? 'Sly Marbo'.
