Works in this franchise with their own pages:
!!Franchise in general:
* AdaptationDisplacement: Occurs frequently due to DolledUpInstallment.
** The first movie was based on the novel ''Nothing Lasts Forever'' by Roderick Thorp.
*** Which itself is a sequel to ''Film/TheDetective'', which itself was turned into a film starring Creator/FrankSinatra.
** The second one was based on the novel ''58 Minutes'' by Walter Wager.
** The third one was originally an unrelated screenplay called ''Simon Says''.
** And the fourth movie was [[BasedOnAnAdviceBook based on a magazine article]] written in ''Wired''.
* SugarWiki/AwesomeMusic: Beethoven's 'Ode to Joy' from the first film. It's also featured in the trailers for all the sequels.
** In terms of music actually written for the movies, Michael Kamen (the first three movies) and Marco Beltrami (who took over following Kamen's untimely demise) turn in some fine work such as Kamen's "The Battle" in the first one and "Shootout And Snowmobile Chase" from the second one, and Beltrami's "Truckzilla" in the fifth.
* ContestedSequel: All of the sequels, to some extent. ''With a Vengeance'', directed [[OnlyTheCreatorDoesItRight again by John McTiernan]], is the least contested. Taken even further with ''A Good Day To Die Hard''.
** This trope is pretty much a given when your villain is being played by Alan Rickman.
** Or Jeremy Irons. In a tank top.
** Katja in ''With A Vengeance''.
** BikerBabe Irina in ''Good Day.''
* GermansLoveDavidHasselhoff: Japan provides the highest foreign box office gross for all four movies, with the highest gross being 81 million dollars for the third movie. [[http://www.youtube.com/watch?v=jIE3dIzypXI The first movie has been spoofed in Japanese media before]], and even Bruce Willis came to Japan to do some commercials.
* HarsherInHindsight: Looking at the first three films: a tower gets blown up, a terrorist plot with airplanes, and New York City as the target of terrorist attacks.
* IronWoobie: [=McClane=] Sr. But he still soldiers on. See Determinator below.
* ItWasHisSled: Most of the films. Yes, including the 4th. Yes, even on this very website, which makes it very difficult to watch the entire series unspoiled.
* WeirdAlEffect: Everybody knows [=McClane=]'s catchphrase "Yippie-Ki-Yay, [[PrecisionFStrike motherfucker]]!", but few now remember that the line (or at least the "Yippie-Ki-Yay" part) was derived from the western song "Git Along, Little Dogies".
* CriticalResearchFailure: The first film features a double-whammy subversion. In the news station, an interviewee claims that the hostages in the building will by now be suffering from Helsinki Syndrome[[note]]Meaning StockholmSyndrome, having mixed up two Scandinavian cities.[[/note]]. The interviewer turns to the camera and smugly says "As in Helsinki, Sweden". [[note]]Helsinki is in Finland.[[/note]] The film then cuts to the cameraman rolling his eyes at the incompetence on display, revealing that the filmmakers were in on the joke.
* FirstInstallmentWins: Every ''Die Hard'' movie has been a hit, but only the first is a landmark in popular culture.
* GenreTurningPoint: The first ''Die Hard'' practically set the standard by which all future action films were judged, in terms of their heroes, [[TheVillainMakesThePlot villains]], etc. On top of that, it even created an action [[DieHardOnAnX subgenre.]]
** Take a look at the cover. [[WebVideo/TheAngryVideoGameNerd What does this remind you of? It kind of looks like...you know...yeah...]] (It shows the Nakatomi tower with an explosion on the top. The dark strip down the middle makes it look at first glance like two skyscrapers of a similar look to the WTC.)
** Powell's backstory involves him mistakenly shooting a 13-year old kid who was waving around a realistic-looking toy gun at night. In 2014 [[https://en.wikipedia.org/wiki/Shooting_of_Tamir_Rice a highly publicized incident]] involved something ''just like this'' happening; a ''12''-year old kid is seen playing around with a realistic-looking toy gun by two police officers who mistake it for a real gun and shoot him in a moment of panic.
* HilariousInHindsight: The actor who played Theo, TheEvilGenius from the first film, eventually quit acting and became a college professor.
* JerkassWoobie: Karl in the first film. He shows real grief and rage when his brother Tony becomes the first baddie [=McClane=] kills, and loses all interest in the robbery for the rest of the film, so bent is he on avenging his sibling, and who wouldn't be furious if their sibling was killed? (True, [=McClane=] only killed Tony in self-defense, but still.)
* MagnificentBastard: Hans Gruber, [[spoiler: especially when he gets caught at gunpoint by [=McClane=] and almost gets away with simply using an American accent to pretend to be a civilian. And even ''then'', after his henchmen turn up, he manages to do some serious damage to [=McClane=] by taking advantage of his bare feet and [[CombatPragmatist shooting the glass]].]] Also, his brother Simon. It runs in the family.
** "Yippie-ki-yay, motherfucker!"
** The formula for the first movie was such an [[HighConcept easily-codified plot]] that other movies could be summed up for pitches or reviews as "DieHardOnAnX".
** [[http://www.cracked.com/blog/5-reasons-die-hard-is-the-best-christmas-movie-ever-made/ People claiming it's one of the best Christmas films ever.]]
** Hans Gruber's attempt [[spoiler: to blow all the hostages away on the roof]] would have been this.
** Or even earlier, when he [[spoiler: casually executes Mr. Takagi, who Hans mentions is a family man]].
* RetroactiveRecognition: Reginald [=VelJohnson=], AKA Sgt. Al Powell, would play the part of patriarch Carl Winslow ([[TypeCasting another police officer]]) in TV's ''FamilyMatters'' a year after ''Film/DieHard'' was released.
