With a three-hour runtime on 'Avengers: Endgame' and a lot of plot and action to get through, it's understandable that you might miss the odd reference or Easter egg.
After all, there are literally 22 movies of potential references to contend with, and some of the ones we noticed were that slight, there might have well been more that we simply missed altogether. With that in mind, here are 12 Easter eggs we noticed in 'Avengers: Endgame'.
CLINT BARTON'S LOW JACK IN THE OPENING SCENE
The low jack/ankle bracelet/whatever you call it was a nod to the events of 'Captain America: Civil War' and the aftermath in 'Ant-Man & The Wasp'. As we know from that movie, pretty much all of the people against Iron Man were placed under house arrest. Natasha Romanoff and Steve Rogers obviously slipped theirs, yet Scott Lang and Clint Barton kept theirs on.
"A GIANT CRACK IN THE SEA BED..."
The scene where Okoye is reporting in to Natasha Romanoff about a giant crack appearing in the ocean near Wakanda has some people have speculating that the film is referencing Namor. For those who don't know, Namor The Sub-Mariner was a Marvel Comics character that - as yet, anyway - hasn't appeared on screen or been specifically referenced. Namor has been around in the world of comics almost as long as Captain America, so it could very well be that this may have been his first appearance.
THE ELEVATOR SCENE FROM 'CAPTAIN AMERICA: THE WINTER SOLDIER'
During the "time-heist" scene where Captain America convinces Jasper Sitwell and Brock Rumlow to give him control of the Space Stone at Stark Tower, there's a clear reference to the elevator scene in 'Captain America: The Winter Soldier'. Of course, this time around, he doesn't need to beat the crap out of anyone. Not only that, in order to convince them that he's one of them, Steve Rogers leans over and whispers the words "Hail Hydra" to Jasper Sitwell. In 2017, a major comic-book storyline involved Captain America being revealed as a HYDRA agent and - yes - proclaiming himself as one by uttering the words, "Hail Hydra".
BUDAPEST WITH NATASHA ROMANOFF AND CLINT BARTON
When Natasha Romanoff and Clint Barton depart for Vormir, he turns to her and laughs that they're "a long way from Budapest". It's never yet been fully explained what happened in Budapest, but it's a nice reference to their relationship and how things have changed so drastically for them both in the intervening years. Our guess is that the standalone 'Black Widow' movie will either give some context as to what happened in Budapest or actually just tell us what happened.
"I CAN DO THIS ALL DAY..."
When Captain America fights himself at Stark Tower, the past-Captain America remarks that he "can do this all day", which the present-Captain America wearily answers back that he knows. This is no doubt a reference to his catchphrase that's come up repeatedly since 'Captain America: The First Avenger' right through to 'Captain America: Civil War'. Speaking of dialogue...
When Captain America calls out to Spider-Man, he refers to him as "Queens" - a callback to a scene in 'Captain America: Civil War' where the two met for the first time. When Rogers asks Parker where he's from, he quickly answers "Queens!" while holding up an aeroplane gangway, to which Rogers replies with a smile, "Brooklyn!".
PARKER AND STARK HUGGING
Is this a reference? Kind of. When Peter Parker and Tony Stark have their first scene together in 'Spider-Man: Homecoming', Parker leans in for a hug when - in fact - Stark was leaning over to push him out of the car, telling him that they're "not there yet." Yet, sure enough, when Stark and Parker are reunited, the first thing Stark does is hug him - concluding that they're now there. N'aww.
"I... AM IRON MAN."
When Tony Stark snaps his fingers and activates the Infinity Gauntlet, his last words on-screen are "And I... am Iron Man." The final scene of 'Iron Man', the movie which kicked off the Marvel Cinematic Universe, saw Tony Stark announce himself to the world as Iron Man - thus completing the circle once and for all.
Before they went on to direct billion-dollar movies like 'Avengers: Endgame', Anthony and Joe Russo were regular directors on the TV sitcom 'Community'. When Rogers infiltrates SHIELD's base in New Jersey in the '70s, he briefly chats with a woman in an elevator played by Yvette Nicole Brown. Later on, a security guard - played by Ken Jeong - clocks Steve Rogers. Both Yvette Nicole Brown and Ken Jeong were main cast members in 'Community'.
FACES AT THE FUNERAL SCENE
Yes, there were plenty of familiar faces in the crowd, but some not so much. For example, William Hurt as Secretary of State Thaddeus 'Thunderbolt' Ross was there, as was Michelle Pfeiffer as Janet Van Dyne next to Michael Douglas as Hank Pym. Also in there was Harley Keener, played by Ty Simpkins. Who's he, you ask? He was the 'kid' from 'Iron Man 3' that Tony befriended when his suit malfunctioned and left him stranded in Tennessee.
In the aftermath of the funeral, Tony Stark's daughter says that she wants "cheeseburgers" when asked by Happy Hogan. In 'Iron Man', the first thing Stark wants after returning home from the cave where he created the first Iron Man suit was - you guessed it - a cheeseburger. In fact...
THAT NOISE AT THE VERY END OF THE CREDITS
While there is no post-credits scene, you do hear a dinging noise at the very end of the credits. It's the same sound effect used when Tony Stark builds the suit in 'Iron Man'. Here's that scene, just for comparison.
