* ActorAllusion:
** In ''Home Alone'', Harry and Marv's van says "Oh-Kay Plumbing and Heating", an allusion to Creator/JoePesci's character, Leo Getz, in the ''Film/LethalWeapon'' sequels, whose favorite catchphrase is "Okay, okay!"
** As the hotel concierge (played by Creator/TimCurry) flees from the hotel room in the second movie when he is threatened by a recording of Kevin's uncle, the recording says "Oh, you're cooking, Frankie!", which is an allusion to Curry's previous role as Dr. Frank N. Furter from ''Film/TheRockyHorrorPictureShow''.
* AdoredByTheNetwork: Up until they were acquired by Creator/{{HBO}}, Creator/ABCFamily often ran the first two movies during ''25 Days of Christmas''.
* AwesomeDearBoy: Why JohnWilliams did the score. FOX passed it along to Williams when looking for a composer, but the crew felt they didn't have a shot to nab the biggest composer in movies to score their moderately-budgted holiday movie. Williams loved the rough cut of the movie and agreed to do the score, while offering him an opportunity to go outside his usual fare with a more Christmas-tinged soundtrack.
* ColbertBump: The Drifters' version of "White Christmas" was featured in the first movie and has enjoyed greater prominence than its original release in 1954. Likewise, the second version featured "It's Beginning to Look a Lot Like Christmas" by Johnny Mathis, leading to increased requests to hear it on radio stations during the holidays ever since.
* TheDanza:
** Catherine O'Hara as Kate [=McCallister=] in the first two films.
** Alex D. Linz as Alex Pruitt in the third.
* {{Defictionalization}}: The [[http://en.wikipedia.org/wiki/Talkboy Talkboy]] from ''Lost in New York'' was originally conceived as a non-working prop for the film; one letter-writing campaign from 1990s kids later, and it was Defictionalized by Tiger Electronics. It sold well enough that several variants were created, such as a [[PinkProductPloy pink-and-purple]] version called the [[DistaffCounterpart Talkgirl.]]
* DoingItForTheArt: Daniel Stern was so committed to the role of Marv, and to the concept of Marv and Harry being the Wet Bandits, that in fact, a number of Marv's antics (sticking snowglobes to the dashboard with gum, stepping on and walking across glass ornaments, trying to pry open the back door with a crowbar before giving up and just opening it, the stupid look on his face before getting hit with a flying paint can, the "Why the hell are you dressed like a chicken?" line he says when he sees Harry covered in feathers) were ad-libbed by Stern.
* DuelingMovies: With Creator/{{Disney}}'s ''Disney/TheRescuersDownUnder'', which opened the same day and had Creator/JohnCandy in it just like ''Home Alone''. ''Home Alone'' prevailed, leading Disney chief Jeffrey Katzenberg to shut down his studio's marketing campaign and blowing up their attempt to continue the ''Rescuers'' franchise (though both films did well on VHS later).
* IAmNotSpock: Macaulay Culkin is now forever associated with this role. In the commentary, he acknowledged it as both a blessing and a curse.
* TheOtherDarrin: Daniel Stern refused to go near the script of the fourth film, so Marv is played by French Stewart. And he's also dressed like Harry, for some reason.
** And, of course, the entire [=McCallister=] family is played by different actors.
*** Linnie [=McCallister=] was actually played by two different actresses, one in each of the first two films.
* RealLifeRelative:
** Kevin's younger cousin Fuller is Macaulay Culkin's little brother Kieran.
** The elf that Kevin meets before talking to Fake Santa in the first movie, and the New York airport desk clerk in the second movie was the then-wife of cinematography Julio Macat.
** A few of director Chris Columbus's relatives also appear in the first two movies as extras.
* SequelGap: ''Home Alone 3'' came out five years after ''Home Alone 2: Lost in New York''. ''Home Alone 4: Taking Back the House'' came out five years after ''3''. Those two are downplayed compared to the ten-year gap in between ''Home Alone: The Holiday Heist'' and ''4''.
* SimilarlyNamedWorks: "Home Alone" is also the name of an unrelated public service video that shows viewers what to do if they're at home by themselves (i.e., if someone calls on the phone, don't say you're home alone, etc).
* StarMakingRole: For Macaulay Culkin.
* TechnologyMarchesOn:
** The first two movies would last 1520 minutes if filmed today; ''cell phones''. Both the DVD commentary and CollegeHumor pointed this out. Instead, the setup would have to involve CellPhonesAreUseless.
** Out of all the valuables in the [=McCallister=] house coveted by the Wet Bandits, Harry mentions that the house likely contains multiple [=VCRs=].
* ThrowItIn[=/=]EnforcedMethodActing:
** Catherine O'Hara forgot her lines in the airplane scene where she realized that they left Kevin [[TitleDrop Home Alone]]. In fact, the iconic shouting of Kevin's name? Her attempt to salvage the take.
** The conversation with the checkout lady and Kevin in the first was improvised. The director didn't say 'Cut', so the actress kept asking him questions and Culkin went along with it.
** Gus Polinsky's story about he and his wife leaving their kid at a funeral parlor all day long was completely ad-libbed by John Candy; matter of fact, many of the moments between he and Catherine O'Hara saw a lot of ad-libbing, as both are ''Series/{{SCTV}}'' alumni.
** The car belonging to the Santa actor actually does stall on camera as he attempts to drive it away.
** Before [[spoiler: [[BigDamnHeroes Old Man Marley saves Kevin from Harry and Marv]],]] Joe Pesci had actually bit one of Macaulay Culkin's fingers, leaving a scar.
* TypeCasting: Be honest, when have you not seen Creator/JoePesci play a criminal?
* UnintentionalPeriodPiece: As any keen viewer will point out today, the plots of the first two ''Home Alone'' films are so strongly reliant on the analog, pre-9/11 world of the early 1990s that they would be largely improbable in the 21st century.
** ''Home Alone''
*** If this film were made in 2012, Kevin's parents could have just called him on a cell phone as soon as they discovered he was missing (his parents discovered he was missing during the flight to Paris; they had to wait until they landed, but were still unable to call the house due to the phone lines being down). And nowadays, people would probably just use the alarms on their phones to wake them up in time, which wouldn't be effected by a power cut.
*** Harry and Marv probably would have never discovered that Kevin was alone at the house (Kevin had fooled them repeatedly into thinking that the house was heavily occupied). It was only after Marv overheard a message from Peter [=McCallister=] being recorded onto an answering machine of the Murphy house while they were burglarizing it that they began to figure out that Kevin was alone in the house and was screwing with them. Answering machines are all but gone today, in favor of private, electronic voicemail, not forgetting that many homes no longer have landline phones anyway.
*** On top of that, the lax airport security of the time is on full display as well. Kate is able to barter a plane ticket off of a fellow traveler ''right in the terminal''; anybody who attempted something like that today would probably be detained on suspicion of being a terrorist. Or, there's the fact that the [=McCallisters=] would have never been able to get through post-9/11 airport security in time to make their flight in the first place, giving them ample time to discover that Kevin is missing and go back home to get him, preventing the plot of the film from ever unfolding.
*** We have Frank tell Peter, "There's no way on Earth we're gonna make this plane. It leaves in 45 minutes" before they get in the vans at their house, located in Winnetka. A Google Maps analysis shows that without traffic it is a half-hour drive from 671 Lincoln Avenue to O'Hare International Airport. Given Chicago's expressways are known to be very congested in both directions at rush hour due to the city's reverse-commute nature, the travel time would actually be closer to an hour. The [=McCallisters=] would have missed their flight by more than a good hour because of the traffic one would face trying to catch a morning flight, and then adding the time it would take for them to check in, print boarding passes, wait in the security line, clear the security checkpoint, and then make their way through Terminal 3 to their gate[[note]]American Airlines is based out of Terminal 3, along with Delta Airlines[[/note]]. There's a reason why the airlines generally recommend that you arrive at the airport a full ''90 minutes'' before your flight.
*** Mocked by WebVideo/HonestTrailers, who encourage you to "bundle up and relive the early 1990s joy of Micro Machines, starting lineup figures, Johnny Carson, 35 mm cameras, landline phones, answering machines, pre-9/11 air travel, and Macaulay Culkin."
*** For a simple answer, this trope is pretty much played straight: director Chris Columbus has said that he and John Hughes wanted very much for ''Home Alone'' to have a "timeless" look and feel to it so that ten, fifteen, twenty, etc. years down the line, it could still be viewed and enjoyed by people and it not seem "dated". Unfortunately, this wasn't the case.
** ''Home Alone 2: Lost in New York''
*** No way in today's world would anyone even consider just letting a kid under age 10 without a parent/guardian around board a fully booked flight to New York. An even more boneheaded move was letting the [=McCallisters=] flight take off with Kevin's unaccompanied baggage, post-Lockerbie (though we don't know if Kevin's baggage was checked to Miami as part of someone else's checked bags).
* WhatCouldHaveBeen:
** According to director Chris Columbus, and early promotion posters, the original ''Home Alone'' music score was to be composed by Bruce Broughton, who ultimately got caught up with scoring ''TheRescuersDownUnder'', and was unavailable to score ''Home Alone''.
** Also, according to Columbus, John Hughes wanted to film ''Home Alone 2'' and ''Home Alone 3'' back-to-back, but TwentiethCenturyFox declined to do so.
*** Hughes' original concept for ''Home Alone 3'' was to be about Harry and Marv doing a HeelFaceTurn, moving to the suburbs, next door to each other, raising their own families, while Kevin does a FaceHeelTurn, and is released from jail, when he decided to exact revenge on Harry and Marv.
** Creator/SigourneyWeaver was considered for the role of Kevin's forgetful mom, but didn't get it. Probably would have clashed with her protectiveness in ''Film/{{Aliens}}'' anyway.
** Harry was written with Creator/RobertDeNiro in mind. Creator/DannyDeVito and Jon Lovitz were also considered for the role.
** [[TheScrooge Uncle Frank]] (who would've been the real mastermind behind the Wet Bandits robbing the McAllister house) was written with [[Series/{{Cheers}} Kelsey]] [[Series/{{Frasier}} Grammer]] in mind.
** And if ''Home Alone 4'' was successful? We would've had a TV series about it on ABC Family. Within the film, Kevin's parents didn't get back together in an earlier script. The ending was rewritten in case they ended up making the show.
** In the commentary for the first film, Chris Columbus said that he had planned for ''Home Alone 3'' to be filmed right after Home Alone 2, which would've starred Macaulay Culkin again (Though it is unknown if there would be any difference between the original idea of ''Home Alone 3'' and the one starring Alex D. Linz).
** According to AMC's ''Story Notes'', Joe Pesci once said that his idea for a third film would be Kevin lost in Hawaii, or a beach resort.
** In the original script, Uncle Frank was the real mastermind behind Harry and Marv robbing the [=McAllister=] house.
** Daniel Stern refused to reprise his role as Marv in the fourth film, saying it was "An insult, total garbage." ''Day-um.'' Keep in mind he has ''Film/AChristmasStory 2'' on his résumé.
