Avengers: Endgame is notable for the box office records it has broken. It was the first film to score one billion nominal dollars within its opening week, and it became the highest-grossing film of all time without adjusting for inflation when it outgrossed James Cameron's 2009 Avatar in nominal dollars on July 20th, 2019. Adjusting for inflation, it is the fifth-highest-grossing film of all time, falling about a billion dollars short of the highest-grossing film of all time with inflation, 1939's Gone with the Wind, and about half a billion dollars short of Avatar.
Mark Ruffalo claimed in one interview that he received multiple different scripts throughout filming just in case he let something slip.note Recall that he actually came within a hair of saying in an interview prior to Thor: Ragnarok that half the universe would die in the next film, and followed it up by bootlegging part of the movie.
Tom Holland was actually only given his lines, after he'd spoiled previous films to the point of it becoming a meme. In scenes involving green screening, he didn't even know who he was talking to. This is why the only actors he actually shared the screen with until the funeral were Robert Downey Jr. and Gwyneth Paltrow.
According to the directors, Tony's funeral was given the production codename "The Wedding". According to Tom Holland during an appearance on Jimmy Kimmel Live, him and the rest of the cast didn't realize it was Tony Stark's funeral until they noticed that Robert Downey Jr. wasn't on set and everyone was wearing black. The only ones at the funeral that knew beforehand were Chris Evans and Gwyneth Paltrow.
Jeremy Renner genuinely didn't know what was happening while shooting the opening scene of Clint's family disappearing, as he hadn't seen the script for Avengers: Infinity War at that point.
A lot of fans misquote Hawkeye's memetic line as "Don't do that. Don't give me hope" whenever good news seems to be on the horizon. That being said, Clint never actually says the first sentence in the film, only saying "Don't..." in a pleading tone before saying the line.
In a similar fashion to the above quote, we have Hulk's quote of "I see this as an absolute win!", also doubling as a visual example thanks to reaction images. While the quote itself is said directly after he says "Time Travel!", reaction images with the quote use the shot from said quote. That said, Hulk never says his memetic line in a cheery way. He only says it after Steve walks away in disapproval.
In the end credits, the original six Avengers are billed last after every other major character, but their names are displayed with much more prestige than any others, and include the written signatures of the actors as well, creating a 'best-for-last' effect. Downey Jr. himself, the man who was the origin of the entire MCU, is billed dead last.
Despite shrinking down and being busy hotwiring his van, Scott can be seen as Giant-Man shoving a Leviathan through a portal in the background as Black Panther is bringing them the Infinity Gauntlet.
During the panning shot of all the heroes assembling behind Captain America, just before the latter turns to face Thanos, you can see that his shield is perfectly circular (when it's actually been broken in half).
California Doubling: New Asgard is in Norway, specifically Tønsberg going by the sign; however, the filming location was the village of St Abbs in Scotland. The giveaway was the back of the truck that Banner and Rocket rode; it still had a UK license plate. The sharp-eyed will notice other nods to Scotland in the background including a distinctive orange-and-blue bottle of Irn-Bru (a distinctively Scottish soda) and the Innis & Gunn beer Thor drinks.
Celebrity Voice Actor: In the Japanese dub, Pepper Potts is voiced by television actress Sayaka Kobayashi.
Content Leak: Days before the film's world premiere, a five-minute clip containing several scenes from the film (mostly from the second and third acts) was leaked all over social media. The Russo brothers issued a letter telling fans again not to spoil the film to others and used the hashtag #DontSpoilTheEndgame.
Downplayed, but Mark Ruffalo has confirmed that he still greatly disliked wearing the mocap suit.
Deleted Role: Katherine Langford was announced to have been cast in an undisclosed role that was later confirmed to be an adult version of Morgan Stark. She filmed her scene during reshoots but it does not appear in the film. The scene would have been them meeting and saying goodbye in the Soul World. The Russos stated it felt too repetitive with the end of the last movie, and it likely didn't help that they needed to contrive a way to let the audience know this was an adult Morgan so they wouldn't be confused at Tony seeming to have a big emotional moment with some random woman.
Tony's death scene was expanded to show the reactions of the other heroes, kneeling and mourning. The scene also confirms that Gamora survived the Battle of Earth and walked away from the group.
A scene where Tony and Pepper are talking about their alpaca (Gerald) who is shown outside eating goji berries they grew. She shoos him out of the kitchen when he starts to interfere jokingly with her cooking and he crashes into something offscreen but they stay cool. Tony goes outside to notify "Madam Secretary" (Morgan) that "lunch is in five".
Two short bits were cut from the heist planning scene.
While discussing the history of the Space Stone, Rhodey asks Steve why he didn't jump out of the HYDRA plane before it crashed.
Rocket calls the Chitauri "the suckiest army in the galaxy" and asks why the Avengers didn't blow up their mothership right away. When Steve says they didn't know that would work, Rocket laughs at them - until Tony shaves a stripe off him.
Additional cut from 1970 New Jersey with Howard asks "Potts" if he wants to work for him. "Potts" (Tony) says he's "a little tied up in futures right now."
There was a version of Vormir in which Thanos' troops were involved and Black Widow had to run with the Gauntlet and be shot while running to jump over the cliff. Joe Russo said it seemed a distraction from the most powerful part of the scene: two friends, one of whom has to die, fighting each other to be the one who dies.
A moment during the final battle where Quill and Rocket reunite and discuss 2014 Gamora.
Thanos grabs Captain America by his neck and chokes him.
An alternate take of the final battle where all of the main heroes gather in a trench to discuss the battle plan. Most of the dialogue still appeared in the final film. The scene was portraying heroes (sans Bucky and Carol - whom both did communicate with the group) hiding out in the mirror dimension to protect themselves from the Sanctuary II aerial bombardment.
When Thor appoints Valkyrie as new ruler of New Asgard before departing with the Guardians of the Galaxy, Valkyrie puts her arm on his shoulder and Thor leans in as if they were about to kiss. This was improvised by both Chris Hemsworth and Tessa Thompson.
Demand Overload: Ticket pre-sales for this movie causedmultiple ticket sites throughout the world to either crash or slow down. To give a perspective on this, the film was able to claim the highest box office pre-sales record in six hours.
Disowned Adaptation: Lou Ferrigno was quite displeased with how Professor Hulk was handled in this movie, citing that the Hulk's scary, hideous appearance was what made the character work.
Enforced Method Acting: When filming the opening scene, nobody told Jeremy Renner that Thanos killed half the universe at the end of Avengers: Infinity War. As such, his portrayal of Clint's confusion at the sudden disappearance of his family is completely genuine.
Co-director Joe Russo claimed that Steve created another alternate timeline when he went back to the 1940s, and then traveled back to the original one after Peggy passed away. Since this take is consistent with the time travel logic explained in the film, most fans defer to this explanation.
Meanwhile, screenwriters Markus and McFeely say they believe that alternate timelines are only created when removing the Infinity Stones (which Steve didn't do on that trip), so it was a Stable Time Loop. In practical terms, this means that Steve was always Peggy's mysterious husband, and Steve did not intervene in history in spite of knowing what would happen (as far as we know) to preserve his timeline. They say that they had always intended this as far back as Winter Soldier,note Which would mean that yes, Steve did make out with his niece-by-marriage. though what actually happened is open to interpretation.
Meanwhile, when asked about the two contradictory takes and which one was accurate, Kevin Feige simply responded to the AMA question with a one-worded answer: "Yes."
Foiler Footage: Initial trailers show Natasha with fully blonde hair during scenes that were eventually revealed to be post-Time Skip. Particularly, she's still blonde when she and Steve see Scott Lang at the front gate.
A lot of fans correctly guessed that the film's subtitle would be Endgame.
Many people guessed the first scene would be Clint's whereabouts when the Snap took place. They also correctly guessed that all of his family would be killed by the Snap, thus leading to him becoming Ronin.
Though it wasn't as widespread as the above, the news that Endgame would feature a five-year Time Skip was correctly guessed based on what little information that was given. Furthermore, the fact that it's permanent is another theory that became true.
Way back in "Thor's hammer" scene in Avengers: Age of Ultron, many people suspected Steve could actually lift Thor's hammer and was merely pretending not to.note Alternatively, it's been theorized that Steve was not yet fully worthy to wield it because he was hiding from Tony that Howard and Maria Stark were killed by the Winter Soldier. As we find out, they were right in the most awesome way possible. Said word-for-word by Thor when it happens.
When the Russos refused to confirm whether or not Jane Foster had survived the snap back in 2018, claiming that it might be a spoiler, some fans theorized that this meant Jane would have a cameo in Endgame. The theory picked up more steam when Natalie Portman unexpectedly showed up at the movie's premiere. In the actual movie, Jane does indeed make an appearance when Thor and Rocket time travel back to Asgard during the events of Thor: The Dark World, made up of both archive footage from that movie and some new dialogue that Portman recorded herself. The screenwriters said in an interview that Jane originally was slated to do more, but that role was given to Frigga instead since it was decidedly more emotional that way, plus (as it was revealed shortly after) there was already a movie with a bigger role for Portman in the works anyway.
After an offhand comment in Ant-Man and the Wasp established the existence of time vortexes in the Quantum Realm, many fans guessed that they would be used to undo the snap somehow. While they didn't end up doing it directly as most theories assumed, they were instrumental in retrieving past versions of the Infinity Stones to handle the job.
Many felt that Bruce and Hulk's arc in Infinity War was building towards Professor Hulk.
Shortly after the release of Infinity War, Kevin Feige explicitly confirmed that the movie would not be called Avengers: The Infinity Gauntlet. The Russos would later indirectly confirm that Avengers: Secret Wars would not be the title of the movie either, as they said that they would be interested in adapting the original comic event a long time after Disney's acquisition of Fox.
When it came to speculation regarding the Time Skip, and the confirmation that Cassie Lang was recast to Emma Fuhrmann, it was widely believed due to the Rule of Drama that Maggie and Paxton would both be victims of the Decimation, so that Cassie would be Conveniently an Orphan. In the movie, though they don't physically appear, both of them were in the half that survived, making Cassie's teenage years only a little less rough.
A key component to a lot of speculation was that the plan would involve a timeline reset as a way of keeping future films consistent. However, while everyone's resurrected, the movie ends in 2023, with all of the dusted characters appearing as they did in 2018. In fact, Tony very explicitly shoots down the idea of resetting the timeline, so that his daughter Morgan (as well as anyone else born in the interim) wouldn't be Retgoned out of existence.
Going further, the fact that Feige once said that he wanted Spider-Man's movies to focus on him in high school, and that Far From Home took place after this movie with him in school, was seen as direct confirmation that everything would return back to normal. In the actual movie, it's established that everyone unsnapped returned as they were five years prior in 2023. Thus, Peter and his friends now attend high school in the early/mid-2020s.
On the opposite end though, some believed that the idea of Peter staying a high school student would be abandoned entirely, before the passage of time was even confirmed, if he survived at all, to the point that some speculated that Spider-Man: Far From Home was an entirely fabricated product meant to keep people from "discovering" that he'd be aged up or not be brought back to life at all.
A popular fan theory was that the time travel elements were actually all just a ruse, with any image suggesting it being dismissed as fake images or staged scenes meant to hide the true plot of the movie. In the end, Occam's Razor won out.
Katherine Langford was believed to have been cast as Kate Bishop once Disney announced her casting as an unnamed character after reshoots. Rumors especially kicked up once a Hawkeye show co-starring the character got announced. Turns out she was actually playing adult Morgan Stark and the scene got cut because test audiences thought it too confusing and repetitive.
There were several theories about Steve getting Mjölnir to budge in Age of Ultron and being able to pick it up here. One was that he could always actually pick it up then but didn't want to either upstage Thor (who at that point was more reliant on it emotionally than he is now) or ruin what was meant to a fun party game. Another was that he wasn't worthy at that specific point because something was weighing down his conscience, probably that he was keeping the fact that Bucky killed Howard and Maria Stark a secret from Tony. Another was that he was almost worthy but needed the events of the later movies to give him a push. The Russos and Kevin Feige would later confirm that it was the first theory, stating that as far as they're concerned, he was always worthy but didn't want to steal Thor's thunder.
After his death in Infinity War many were theorizing that Loki would end up pulling one of his old tricks. With one theory suggesting he took Bruce's place throughout Infinity War while the real Hulk was with the surviving Asgardians. This not the case on both accounts, the movie makes it clear that it really was Bruce the whole time and Loki the audience has been following since the original Thor did indeed die. But there is a bit of ambiguity regarding the Loki from 2012 that escaped with the Tesseract.
Keep Circulating the Tapes: The deleted scene with Professor Hulk rescuing people from a building fire was only shown after the credits of the film's re-release, with the only copies of it online being smartphone recordings the scene uploaded to video-sharing sites.
The Russo Brotherssaid that the title of the fourth Avengers film was not mentioned in the dialogue of Infinity War. Cue the first trailer revealing that Endgame is the subtitle, itself derived from a quote from Doctor Strange: "We're in the endgame now". Possibly a case of Flip-Flop of God, as rumors suggested that several titles were up for consideration.
The Russos also said that no characters from the TV shows would appear. Edwin Jarvis makes a cameo.
Angela Bassett said that Shuri survived the Snap. This movie shows that she was in fact killed by it. However, Bassett might have actually just been wrong instead of lying (many of the actors were actually given false information on who lived and who got dusted to minimize the chance for accidental spoilers; for instance, Chadwick Boseman was assured T'Challa survived Infinity War and it wasn't until he watched the movie at the premiere that he learned his character got dusted).
In the trailer, Natasha is seen practicing shooting at a target, but this scene is not included in the movie.
A scene with Thor in his Infinity War look holding Stormbreaker and powering up with lightning doesn't appear.
The Stinger of Captain Marvel, in which Carol appears before the Avengers asking for Fury, appeared to have been a clip from Endgamenote akin to the stinger of Ant-Man showcasing an edited clip from Captain America: Civil War. However, the scene does not appear in the film itself and Carol is instead introduced in a very different manner. However, given that Carol was apparently asked to find Tony at some point, it's entirely possible the Captain Marvel stinger took place prior to Stark and Nebula's rescue.
The scene from a trailer where Natasha sits outside of the Avengers compound while it's raining doesn't appear in the movie.
There is a shot of Steve uncharacteristically getting quietly angry that takes place during the support group meeting scene that isn't in the movie.
In the second trailer you can hear Thor saying "I saw all these people die", but he never says it in the actual movie.
In the second trailer, Tony and Steve shake hands after Tony asks "Do you trust me?" and Steve answers "I do." In the movie, they don't shake hands in this scene.
By the time Endgame was released, Peggy Carter's voice actress in that dub on all previous appearances in the MCU, Christine Byrd, had retired (in fact, dubbing Peggy on Agent Carter, Peggy's last proper appearance in the MCU before this film, was Byrd's final dubbing credit). As a result, in this film Peggy is dubbed by Betzabé Jara.
After Alexis Ortega dubbed Spider-Man in his threepreviousappearances in the MCU, Alberto Bernal replaces him in the role in this film.note Ortega in fact hasn't worked in dubbing ever since, and Bernal would also dub Spider-Man in Spider-Man: Far From Home, making this replacement seemingly permanent.
In Agent Carter, Edwin Jarvis was voiced by Dafnis Fernández, but here he is voiced by Jaime Alberto Carrillo, due to both works being dubbed in different studios (specifically, Agent Carter's dub wasn't produced by Disney).
In the Japanese dub, Hiroe Oka voiced Pepper Potts in all of her previous appearances in the MCU. However, she announced her retirement in February 2019 due to spasmodic dysphonia. As such, Pepper is dubbed by Sayaka Kobayashi in Endgame.
Real-Life Relative: Lila Barton is portrayed by Ava Russo, daughter of co-director Joe Russo. Another daughter, Lia, and Anthony Russo's son Julian appear in the scene where a group of children ask Professor Hulk for a selfie. Joe Russo's oldest two children, Sophia and Basil, appear at the memorial scene.
Refitted for Sequel: The opening scene with the Barton family was originally planned for Infinity War, but then Joe Russo decided to make it this film's first scene. The writers all felt that Hawkeye's character became more dramatically impactful after the snap whereas his arc in IW would have repeated beats from Civil War, i.e. a hero coming out of a 10-Minute Retirement.
Release Date Change: The original release date was May 3, 2019. However, following the success of the opening of Avengers: Infinity War in the last full week of April, Marvel opted to replicate that move here.
Scully Box: Even though the character is CGI, in order for Rocket to be at eye level with the much taller actors surrounding him, most of Rocket's scenes have him standing on tables, chairs, couches, etc. Even at Tony's funeral, he's standing on a stump.
Most of the merchandise depicting War Machine's Mark 6 armor from the final battle (including the Marvel Legends version) got the colors wrong, showing the suit in black and silver instead of red, white and blue. Presumably, the production team's decision to use the Iron Patriot-inspired color scheme in the actual film was only made after the toy companies had already been given reference materials to base their products on.
Likewise, the majority of the action figures based on the Quantum Realm suits had them colored primarily gray/silver instead of white. Like the War Machine issue, this was likely a case of plans for the suits (which were created via CGI in post-production) changing after the toys had already been designed.
The toy line also spoiled the plot point about the Avengers using Stark technology to create a new Infinity Gauntlet.
Pepper's Rescue armor was also first revealed when a prototype of the Rescue action figure leaked online.
The focus on Thanos showing up primarily in his battle armor and wielding a double-bladed sword was spoiled by multiple toylines. However, most merchandise depicts him with the Infinity Gauntlet to conceal the fact that he's actually a time-traveling past Thanos.
Teasing Creator: Mark Ruffalo, known for accidentally spoiling stuff about these movies, went on The Tonight Show to share the title... Which was censored for the broadcast. Following this, he went all-out and described an action sequence which was almost entirely censored while he hammed it up on the stage.
In the script, Tony performed his Heroic Sacrifice in complete silence. Just a few months before release, the Russos figured that a character known for constantly quipping should say something at that moment, and it was editor Jeff Ford who had the obvious-in-retrospect idea of making it a retort to Thanos's "I am inevitable" refrain that also tied into the famous final line of the first MCU film.
Also, the line "I love you 3000" was originally written as "Love you tons". You can thank Robert Downey Jr. for the word change, since that is what his children actually say to him in real life.note Which means that the fact that all the Marvel movies total up to 3000 minutes is just an amazing coincidence.
And one more from Downey, while filming the early argument between Tony and Steve, he got so worked up in character that he snapped out an unscripted "Liar!" to everyones genuine shock.
When asked about the Nova Corps being in the Final Battle, the Russos went ahead with pointing out that not only are the Novas in there, but they also claim to have included Richard Rider himself...somewhere in the background.
Someone asked the Russos if Hulk hit anyone when he threw the bench. They replied that he hit Frank Castle.
2014 timeline Thanos and Ebony Maw were able to figure out how to synthesize Pym Particles and subsequently mass-produce them in order to make the jump into the prime timeline.
When Captain America traveled back to the alternate 2014 to return the Soul Stone to Vormir, he met again with Red Skull, but they weren't hostile to each other, as it was Rogers' mission to deliver to stone back while Red Skull's mission was to guard it, adding that Red Skull is no longer the same as he was in Captain America: The First Avenger, with his only purpose now being to guard the Soul Stone.
By traveling back to the 1940s, Captain America created a new branched reality where there were two Captain Americas: the one we met in The First Avenger and another one who was encased in ice. However, the Russos refuse to state what happened in that new timeline, saying that it's a story for another time.
According to Stephen McFeely and Christopher Markus, the Snap also affected other dimensions like the Quantum Realm, stating that Ant-Man's survival wasn't because he was trapped there, he was simply lucky.
The Russos stated that Steve was always worthy of Mjölnir, and just didn't pick it up until now because it would have made Thor feel less special. Kevin Feige later confirmed this in an AMA on Reddit as well and Joss Whedon revealed that this was his intention with the party scene back in Avengers: Age of Ultron.
Joe Russo stated that upon using the Tesseract to escape custody, the 2012 Loki created a branched new reality in an alternate timeline, and that they don't know if Captain America was able to find Loki upon traveling back to that timeline to deliver back to the Time, the Mind and the Space Stones.
After Spider-Man: Far From Home showed that the un-snapped people were brought back right where they were before, some fans got worried about the implications for the likes of people who were in airplanes at the time. It was then stated that Bruce made sure that everyone who was brought back was in a safe position.
According to a Twitter post by the Russo Brothers, Noobmaster69 is Wong. Prior to this, a favorite fan theory was that he was Deadpool.
According to Kevin Feige, Thanos's use of the gauntlet to wipe out half of all life in the universe is called the Snap - which aligns which what MCU fans have been calling it, the use of the gauntlet by Banner to reverse it is identified as the Blip.
According to Jim Starlin, Thanos' double-bladed sword and the twirling motion used to block Iron Man's blasts were shout-outs to the rotors on the Thanoscopter.
The Russos stated in an interview that Richard Rider and the Nova Corps were canonically present for the Battle against Thanos' forces at the end, even though they were never seen on screen.
It was stated that after Captain Marvel's stinger, the Avengers filled Carol in on what had been going on, and from then, she used a tracker given to her (likely by Rocket), in order to find Tony and Nebula in space.
Yvette Nicole Brown has named her character, the woman in the elevator at Camp Lehigh in the 1970s, Phyllis, and Phyllis is a real S.H.I.E.L.D. agent, not a HYDRA agent.
According to Ty Simpkins, it's likely that during the funeral, Harley Keener thought that having been in touch with Tony Stark all those years, he had come to see him not only as a mentor, but as the only father figure he ever had, as Iron Man 3 previously stated that his father left him.
Dave Bautistaopined that though glad that Thanos is no more, Drax possibly felt a bit unsatisfied that he wasn't the one who killed Thanos at the end, yet he anyway honored Tony Stark's sacrifice.
Spider-Man: Far From Home writer Chris McKenna opined that apart from decimating half animal life in the universe, the Snap also affected some of the bacteria in the survivors' digestive systems.
And the working title used to hide the production was Mary Lou 2 (Infinity War was titled Mary Lou).
More specifically, arguably the most spoiler-heavy scene in the movie — the funeral of Tony Stark — was listed as "The Wedding" in all the information given to actors until time came to actually film it.
