Marvel Studios considered killing Tony Stark in 2018’s Avengers: Infinity War before ultimately deciding to save his death for the following film, Avengers: Endgame. According to director Joe Russo, the creative team debated the move to heighten the stakes of the conflict with Thanos, though they ultimately chose to defer the sacrifice to maximize its narrative impact in the subsequent sequel.
Why the Russo Brothers Considered an Early Exit for Iron Man
The creative team behind the Infinity Saga frequently experimented with major plot points during the writing process. Joe Russo confirmed to CBR that the writers explored "all angles" for the conclusion of Infinity War. While a scene exists where Thanos impales Tony Stark on the planet Titan, the character ultimately survived the encounter.

"There was a moment where we thought, ‘They’re not expecting it. This could be the best place to possibly do it,’" Joe Russo told CBR. The team ultimately decided that moving the character’s final moment to Endgame allowed for a more complete arc, leading to the definitive conclusion where Stark uses the Infinity Stones to defeat Thanos.
How Marvel Studios Balances Stakes and Storytelling
The decision to keep Robert Downey Jr.’s character alive for one additional film reflects a long-standing Marvel Studios approach: the "best idea wins" philosophy. By stretching the narrative "taffy," as Joe Russo described the process, the studio managed to preserve the emotional weight of Stark’s eventual departure.

This strategy contrasts with typical blockbuster production cycles, where scripts are often locked months before cameras roll. In this instance, the flexibility allowed the filmmakers to pivot away from a shock-value death in 2018 toward a more earned, legacy-defining sacrifice in 2019.
Did you know? The Avengers: Infinity War production team held multiple internal debates regarding the fate of core cast members to ensure the stakes felt genuine without compromising the long-term trajectory of the MCU.
What to Expect from Robert Downey Jr.’s MCU Return
Robert Downey Jr. is scheduled to return to the Marvel Cinematic Universe as Victor Von Doom in Avengers: Doomsday. This casting choice represents a significant shift for the franchise, as the studio brings back its foundational star to portray the primary antagonist.
Industry analysts observe that this move is designed to mirror the excitement generated by the Russo Brothers’ previous work on Infinity War and Endgame. By reuniting the directors with the actor who launched the franchise, Marvel aims to recapture the audience investment that defined the end of the Infinity Saga.
