“Iron Man” was the first “Avengers” film in the Marvel Cinematic Universe. “Avengers: Endgame” bookends what was started in “Iron Man” to bring the films to their conclusion.

In an interview with Howard Stern in 2016, Downey responded to a question about how he would feel if Marvel replaced him as Iron Man.

“If you’d ask me in 2008, 2009, 2010 how I felt about it, I would say that I was the Atlas of the Marvel Universe, I was holding it up, they should erect a shrine in my honor, blah, blah, blah. Whatever,” Downey said. “I really just got to be the frontman in a band that was gonna be in the Hall of Fame no matter what.”
