“And I… Am… Iron Man” (Avengers: Endgame)
In one of the most pivotal scenes in Avengers: Endgame, Thanos reprises one of his lines from Avengers: Infinity War by saying, “I am inevitable.” In the script, Iron Man was supposed to simply snap his fingers in response and say nothing. However, the producers felt like the scene was missing something.
So they decided to also give Iron Man a reprised line, which was a throwback to the original 2008 Iron Man movie: “And I… Am… Iron Man.” While the line may lack originality, it did make the scene a whole lot better.
