* The cast mentions multiple TimeTravel works while planning the Time Heist, including ''Film/BackToTheFuture1'', ''Franchise/StarTrek'', ''Film/BillAndTedsExcellentAdventure'', ''Film/TheTerminator'', ''Film/{{Timecop}}'', ''Literature/AWrinkleInTime'' (specifically the sequel books, but that's not mentioned), ''Film/SomewhereInTime'', ''Series/QuantumLeap'', ''Film/HotTubTimeMachine'' and ''Film/DieHard'', only for Scott to remember that [[OneOfTheseIsNotLikeTheOthers the last one isn't actually a time-travel movie.]]

** Furthermore, whilst ''Film/AvengersEndgame'' goes to great lengths to lampshade that time travel does not work in the same way, the plot of the movie (particularly during the second act) borrows elements liberally from ''Film/BackToTheFuturePartII'': both films revolve around the heroes [[BackToTheEarlyInstallment having to go back to events and locations from the past that are connected to them]], to retrieve one or more {{MacGuffin}}s, [[NeverTheSelvesShallMeet encountering and avoiding their past selves or (in Thor and Tony's cases) their parents]], in order to thwart a BadFuture caused by said {{MacGuffin}}(s) falling into the hands of the BigBad, and a younger iteration of said BigBad acting as a SpannerInTheWorks in the finale.

** [[https://twitter.com/Avengers/status/1157496053291089922 Kevin Feige]] cites the ''Series/StarTrekTheNextGeneration'' series finale ''[[Recap/StarTrekTheNextGenerationS7E24AllGoodThings All Good Things...]]" as an inspiration for the five-year TimeSkip, allowing us a glimpse into the future. That finale is ''also'' a TimeTravelEpisode allowing the show to revisit, re-live and (occasionally) revise past triumphs, much as this film does.

* In an interview with [=SModcast=], writers Markus and [=McFeely=] revealed that the credits with the signatures of the original five Avengers is a shout-out to the credits of ''Film/StarTrekVITheUndiscoveredCountry''.

* [[TheNicknamer Tony]] cheekily compares Nebula to a "Blue Meanie" from Music/TheBeatles Animated Movie ''WesternAnimation/YellowSubmarine'' in his recorded will to Pepper. In the French version, he calls her [[Franchise/TheSmurfs the Smurfette]] instead. He referred to Ant-Man as ''Literature/{{Thumbelina}}'' and ''Film/StuartLittle''. He also snarkily calls Thor (after five years of letting himself go and drinking like crazy) "[[Film/TheBigLebowski Lebowski]]".

* Iron Man being the one to deliver the finishing blow against Thanos may be a reference to the fact that the villains first appearance was in an Iron Man comic book.

** When Bruce and Rocket visit Thor in New Asgard, the latter initially thinks that it's someone to fix the cable. In ''Film/TheBigLebowski'' there's a scene in which the titular character, whom Thor now resembles, watches and discusses the intro of an adult movie where the male actor states that he's there to fix the cable.
** Thor's roommates Miek and Korg are playing ''VideoGame/{{Fortnite}}''.
** The grand plan to jump back in time and snatch the Infinity Stones is referred to as a "[[Recap/DoctorWhoS34E5TimeHeist Time Heist]]".

** When Tony checks on Rocket's repair work leading up to the Time Heist, he calls him "[[Franchise/RatchetAndClank Ratchet]]", to which Rocket annoyingly replies "It's ''Rocket'', not Ratchet!". Both are small, fuzzy, gun-toting aliens with an itchy trigger finger. Naturally, Creator/InsomniacGames ran with it and put up a "Ratchet, not Rocket" shirt on their store.
** Rhodey warns Nebula about there may be traps in the vault housing the Orb/Power Stone. There weren't any (aside from the shield around the Orb), but the traps that he thought of are lifted from ''Film/RaidersOfTheLostArk''.
** Nebula, after reaching through the energy shield guarding the Power Stone, melts the synthetic flesh off her right arm, which now bears an ''exact'' resemblance to the T-800's metal endoskeleton arm from ''Film/Terminator2JudgmentDay''. That scene is also similar to ''Film/IRobot'' where Sonny reaches into a forcefield to obtain the nanites needed to kill the BigBad.
** Joe Russo revealed in an Empire podcast episode that the scene where Thanos sits talking on a stump while Tony, Steve and Thor approach is an homage to ''Film/OnceUponATimeInTheWest''.
** Thanos's double-bladed sword, which can be hurled like a giant shuriken/buzzsaw through his enemies and then returns to his hand on command, resembles and functions almost ''exactly'' like the similar sword wielded by Tessai the rock-monster from the 1993 anime classic ''Anime/NinjaScroll''.
** Iron Man being the one to deliver the finishing blow against Thanos may be a reference to the fact that the villains first appearance was in an Iron Man comic book.
** The animation of the Leviathan about to devour Rocket right before getting turned to dust by Tony's snap [[https://www.reddit.com/r/marvelstudios/comments/dt0zad/did_anyone_else_catch_this_visual_reference_to/ looks exactly like]] the animation of the holographic ''Jaws'' advertisement attacking Marty in ''Film/BackToTheFuturePartII''.
