Full spoilers ahead for Avengers: Endgame!
Avengers: Endgame screenwriters Christopher Markus and Stephen McFeely are talking about the decisions they made when scripting the final installment of the original MCU Avengers, and that includes why Robert Downey Jr.’s Tony Stark/Iron Man was killed off during the film’s climax.
In a must-read interview with The New York Times, the writers talked about why Tony was always slated to die in Endgame.
“The watchword was, end this chapter, and he started the chapter,” said McFeely of Iron Man. Of course, that is true as Downey Jr. launched the MCU all the way back in 2008 with the first Iron Man film. At the time it would’ve been impossible to predict how far this shared universe of heroes and villains would go. But the fact is, Tony was the start of it all.
