Almost no comic book movie is as revered and praised as The Avengers. Connecting 5 years of films, it was the true birth of the MCU, as well as the trend of cinematic universes. Filled to the brim with easter eggs and references, one wouldn't think the movie could get any better, but it has.
While scrolling through IMDb's page for trivia on The Avengers, I came across a very interesting point: during the Helicarrier argument scene, many comments that were thrown out would directly foreshadow future Marvel movies. I'll explain each movie's reference when I get to it, but here's what the user started with:
While Fury and the Avengers are arguing with each other on the Helicarrier, characters throw certain remarks that coincidentally foreshadow plot points in subsequent films.
Anything in the "foreshadowing" tag below is an exact quote from the trivia. Ready? Let's begin:
Iron Man 3
Captain America (to Iron Man): Big man in a suit of armour. Take that off, what are you?
Foreshadowing: Steve asks Tony what he is without his armor, a topic deeply analyzed in Iron Man 3.
What Steve Rogers said to Tony Stark in that scene is probably one of the most important pieces of dialogue in the whole movie, teasing Civil War 4 years in advance. More than that though, it was exactly the question asked in Iron Man 3. Being the first movie after The Avengers, it was quite obvious this movie would have the most direct fallout from it, but it still revealed quite a bit (although we didn't know it at the time).
Thor: The Dark World
Foreshadowing: Fury aggressively chastised Thor about foreign species going to his planet to "blow stuff up", which comes into play in Thor: The Dark World (2013) with the invasion of Asgard and Earth by the Dark Elves.
Thor: I thought humans were more evolved than this.
Nick Fury: Excuse me, did WE come to YOUR planet and blow stuff up?
Admittedly, this isthe weakest of the three, but there's a reason it was said. Nick Fury clearly knew something was going to happen, and boy was he right, because in Thor's next solo outing, guess what was attacked? Asgard, by a "foreign species". Maybe his other eyeball keeps an eye on the mystical side of
Captain America: The Winter Soldier
Foreshadowing: The most unassuming one (which is ironically translated into the biggest plot point in the whole cinematic universe) is when Bruce asks Natasha if Captain America is on threat watch, to which she replies "we all are." In Captain America: The Winter Soldier (2014), Steve (and by extension, Natasha herself) becomes a fugitive of S.H.I.E.L.D. after the murder of Nick Fury. Natasha also mentions that S.H.I.E.L.D. monitors potential threats, which plays heavily into this film as well.
Natasha Romanoff: [all arguing in the lab] Are you really that dense? S.H.I.E.L.D. monitors potential threats.
Bruce Banner: Captain America is on threat watch?
Natasha Romanoff: We ALL are!
This is my favorite one, because of how quietly
and quickly it's said. It's a minor interaction between minor players that had the biggest effects on a movie. While it was enough to say that SHIELD monitors potential threats (like when Jasper Sitwell spit out a string of names), they took it a step further and said they're all monitored. Interestingly enough, Black Widow knew this information, even while SHIELD "wasn't" corrupt. Is it possible this was HYDRA's inside plan the whole time? To get rid of the Avengers by making them fugitives? And if so, how did Black Widow know this? Asks a lot about her ties to HYDRA, doesn't it?
So that's something that I found really interesting, let me know what you think in the comments!
