Avengers: Infinity War was the MCU movie that was based on the plot that was set up by all the previous MCU movies. While the movie only picked up specifically from a few MCU movies that had come out prior to Infinity War, it still directly took references from almost all of the 18 movies that have come out before.
There were a whole lot of references that have been used in previous movies and popped up in different contexts here. For starters, the movie began with one where Loki used the quote “We have a Hulk!” after distracting Thanos and this was actually used upon him previously by Tony.
Many other came into play and here are some of the examples – “On your left”, “Dance-Off”, “Fine, I’ll do it myself!”, and many more dialogues were used. While these were some direct references, some dialogues in Infinity War referred indirectly to the previous movies. One of the major dialogues in the movie which was used by Doctor Strange was actually more than just a reference for MCU as it also hinted at the plot of the next movie.
Right from the beginning of the MCU, Iron Man has been the heart of it and he has led from the front along with Captain America. While at first, Tony did fight for himself for a while, but ever since the battle of New York happened, he actually got aware of the competition that exists outside of Earth, and the threat that this competition poses upon the planet.
He got out of his cocoon and evolved, looking at the bigger picture. While most people on the planet were thinking about themselves, Tony was coming up with strategies and plans that would prevent Earth and the people living in it. In order to do that, he unwittingly unleashed a murder bot upon the planet, but he built another android to stop that catastrophe.
He is now ready to sacrifice himself for the greater good and he actually carries the weight of the world upon his shoulders. This is why it was really crucial for him to survive Infinity War. Doctor Strange did not actually believe in Tony at first, being adamant to protect the Time Stone if it came to a choice. But having seen the future, Strange came to know how important Tony is in the future.
Tony was about to die a noble death at the hands of Thanos, but Strange saved him because he actually saw the future where the Avengers would win against Thanos, and for that future to happen, they actually had to lose the first battle. He gave Thanos the Time Stone and right at that moment, he told Tony that they were in the “End Game” now.
This could be just a reference but Strange actually used this particular phrase for a reason. He stole it from Tony himself as he had also said something similar back in Avengers: Age of Ultron. Here’s what Tony said back then:
“A hostile alien army came charging in through a hole in space… we’re standing 300 feet below it. We’re the Avengers. We can bust arms dealers all the live-long day, but… that up there? That’s the end game. How were you guys planning on beating that?”
Here Tony meant the aliens living outside of Earth to be the ultimate End Game. Strange being the one to have seen the future used this particular phrase to hint Tony about something. This is why Tony was left alive. He will actually focus upon Strange’s last few dialogues, particularly the ones that say “End Game” and “There was no other way”.
Since Avengers 4 will be a big Time Travel event, references could come into play in the upcoming movie. We don’t exactly know what all is going to happen, but Tony is probably going to be the most important aspect of Avengers 4.
The movie comes out on May 3, 2019, and here’s the Synopsis:
“A culmination of 22 interconnected films, the fourth installment of the Avengers saga will draw audiences to witness the turning point of this epic journey. Our beloved heroes will truly understand how fragile this reality is and the sacrifices that must be made to uphold it.”
