Warning: this article contains spoilers for Avengers: Endgame!
Avengers: Endgame is the culmination of 11 years and more than 20 movies. It seems only fitting that the film’s middle act revolved around the Avengers travelling back in time and revisiting some of their greatest battles. But as screenwriters Christopher Markus and Stephen McFeely revealed, Endgame’s time travel sequences almost went in a very different direction.
In an interview with The New York Times, Markus and McFeely discussed the ways in which their original plans for Endgame’s time travel locations changed during the writing process. It turns out that the duo didn’t originally plan on revisiting the Battle of New York in 2012’s The Avengers. Instead, the first draft featured Iron Man travelling to Asgard with Thor to collect the Aether and the Tesseract.
