Robert Downey Jr. didn’t want to film Iron Man’s iconic last scene in Avengers: Endgame from the outset. In 2008, Jon Favreau started off the MCU with Iron Man, appearing the actor as Tony Stark. From that point forward, Downey has assumed the part multiple times throughout the span of 11 years. He covered it off in 2019 in Joe and Anthony Russo’s Avengers: Endgame, which additionally denoted the end of the Infinity Saga.
It’s important that in the first Endgame cut, Iron Man remained silent. In any case, as the Russos were altering the movie, they concocted the possibility of the legend expressing his iconic line. It had been a really long time since filming wrapped up, so when Downey was educated regarding the arranged reshoots, the actor would not like to do it. MCU plan Kevin Feige and Anthony Russo separate the motivation behind why in the new book The Story of Marvel Studios: The Making of the Marvel Cinematic Universe (by means of ComicBook). Understand what they said underneath:
As clarified by Anthony Russo, Downey would not like to shoot the scene since he would not like to typify the person once more. Filming Avengers: Infinity War and Avengers: Endgame was enthusiastic for all interested parties, particularly since it’s the zenith of the MCU’s first decade of storytelling. However, it’s almost certainly correct that it was extra hard for Downey since he’d been in the establishment since the start. Knowing that his time as Iron Man was ending would’ve been troublesome since he epitomized the job for over ten years, and to be honest, it likewise changed for what seems like forever. Downey wasn’t simply getting back to film an arbitrary scene; this was Iron Man’s last pivotal turning point, so it required intellectually planning for it. Making things such a ton harder is the way that they reshot the previously mentioned scene after he consented to return at a phase in Raleigh Studio in Los Angeles. It is contiguous the one that he test evaluated for Iron Man back in the last part of the 2000s, which would’ve most certainly evoked nostalgia.
Marvel Studios has ways to bring back Downey into the MCU assuming they want to. The multiverse offers account freedoms to do that without strolling back on Iron Man’s passing in Avengers: Endgame. In any case, however enticing as it seems to be, it’s better in the event that they don’t, particularly since it hasn’t been that since a long time ago his rather all around done last curtain call. Regardless, in spite of not having an actual presence in the establishment, Tony Stark’s quality poses a potential threat as his heritage keeps on affecting the eventual fate of the universe.
