Trivia: Spoilers: Captain America being worthy of lifting Thor's hammer Mjölnir is something that is pulled from the pages of the comics directly, most notably in this context the Civil War comics. He'd previously been able to move it fractionally in Age of Ultron - Joss Whedon has implied he was able to lift it the whole time, just pretended he couldn't so as to spare Thor's feelings.
Trivia: Spoiler! After Tony snaps his fingers at the end, a scene was filmed with him having a vision of his daughter Morgan, now grown up, played by 13 Reasons Why star Katherine Langford. Much like Thanos' conversation with a young Gamora in Infinity War, Tony and Morgan would discuss what he'd just done and she'd forgive him, putting him at peace. The scene was ultimately scrapped because there wasn't the emotional connection with an adult version of his daughter, and the Russos dismissed it as "too many ideas in an overly complicated movie."
Trivia: When Steve is watching Peggy through the glass, she mentions that Braddock "hasn't checked in." This is likely a reference to Brian Braddock, known as Captain Britain in Marvel comics. No confirmation that he'll be appearing any time soon - might just be an Easter egg for the fans - but Kevin Feige has mentioned discussions relating to him and the MCU before.
Trivia: Spoilers! The prophecy/vision in Age of Ultron is semi-fulfilled in this film and Infinity War - Captain America's shield is broken in half, Hulk is unable to fight, Black Widow lies on her back in death, same as here, and Thor is in the same position when injured by Thanos as he appears in the vision.
Trivia: MCU producer Kevin Feige has said inspiration for this movie came from "All Good Things", the series finale of Star Trek: The Next Generation.
Trivia: Spoilers: Robert Redford briefly appears in a cameo as Alexander Pierce, reprising his role from "Captain America: The Winter Soldier." Out of a career spanning nearly sixty years, this is the only time Redford has reprised a role in a sequel to one of his films.
Trivia: The time travel suits were inspired by the "The Avengers: Earth's Mightiest Heroes" cartoon series.
Trivia: When Hank Pym is shown in 1970 New Jersey, the camera sweeps across his desk, and the original Ant Man helmet is briefly on screen.
Trivia: During the climactic battle, before Doctor Strange returns with the other restored heroes, there is a wide shot of Captain America all by his lonesome walking towards Thanos. This is similar to a scene from the "Infinity Gauntlet" story, where amongst a slew of defeated heroes, Cap defiantly walks right up to Thanos and tells him he will never be able claim victory as long as at least one person stands against him.
Trivia: Thanos loses his hand - someone's lost a limb in nearly every MCU film since Iron Man 3.
Suggested correction: With the exception of Bucky in Civil War and Maw's buddy in Infinity War, only in the Phase 2 movies has someone lost an arm in every movie.
Klaw has his metal arm removed in Black Panther.
Trivia: While Peter and Ned are hugging in the school there is blond girl behind them wearing a Spider-Man skirt.
Suggested correction: It's not a Spider-Man skirt. It's just a skirt with a black and white spider web design. Especially since the black suit was not something that has happened yet in universe.
Trivia: Spoilers! Tony Stark's line at the end "And I am Iron Man" wasn't in the script, in fact it wasn't even originally filmed, he just snapped his fingers. When editing the final battle together, the directors realised something was missing, and editor Jeff Ford suggested bringing his arc full circle with that line. They filmed it as part of reshoots, only a few months before the movie was released.
Trivia: In September 2018, before the title was announced, the Russo brothers posted an image of the set on Twitter, with the caption "Look Hard." Eagle-eyed fans worked out that shapes within the image spelled out "Endgame," later confirmed by the Russos.
Trivia: Marvel has been responsible for the first film to gross over $100 million in its domestic opening weekend (2002's "Spider-Man", albeit made by Sony), the first film to gross over $200 million in its domestic opening weekend (2012's "The Avengers") and the first film to gross over $300 million in its domestic opening weekend with this film, "Avengers: Endgame." "Endgame" also holds the record for the quickest film to reach $2 billion, reaching the rare number at the end of its second weekend.
Trivia: The title "Endgame" has been teased in two previous Avengers films - most obviously in Infinity War, when Dr. Strange says "we're in the endgame now", but it actually originates more significantly in Age of Ultron, when Tony says "We can bust arms dealers all the livelong day, but that up there... that's the endgame."
Trivia: Spoiler! Howard Stark's butler/driver Jarvis appearing marks a rare, maybe even only, instance of a character from a Marvel TV show appearing in the films. He was a main character in the Agent Carter TV series.
Trivia: With this film and counting cameos, Chris Evans will have appeared on-screen as Captain America in at least one film a year between 2011 and 2019. With this film, Tom Holland will also become the actor who has portrayed Peter Parker/Spider-Man in the most films with his fourth appearance as the character - he will beat the previous record held by Tobey Maguire, who appeared as the character in the three films of the original "Spider-Man" trilogy.
