Filming for Avengers: Doomsday has been ongoing in the UK since April, but recent developments reveal complications behind the scenes. Reports have surfaced that Robert Downey Jr. made significant demands for reshoots, shaping the production’s direction amid rising tensions on set. The focus keyword, Robert Downey Jr reshoots demands, highlights the actor’s insistence on personally filming his scenes, influencing Marvel and Disney’s decision to schedule three additional weeks of shooting.
Robert Downey Jr.’s Decision to Reshoot Key Scenes Personally
Initially, the plan was to film many of Downey’s scenes using a stand-in, with the actor providing off-camera voice work. However, after two to three weeks of relying on a body double and a face double, Downey expressed dissatisfaction with the arrangement.
They had a body double and a face double, and Robert would stand outside the scene reading the lines. And apparently, after two or three weeks, he said, ‘This isn’t working. I want to shoot the whole thing with me in the suit.’

Following Downey’s insistence, Marvel and Disney agreed to reshoot substantial portions of the film with him in character, demonstrating his influence on the production decisions. Directors Joe and Anthony Russo supported this change, emphasizing that Downey’s involvement was crucial for the movie’s quality.

Ego and Tension Among Cast Members Affecting Production
Beyond Downey’s demands, the set has encountered notable dysfunction tied to strong personalities and clashing egos. Insider reports compare the atmosphere to that of the high-energy action franchise Fast and Furious, where on-set conflicts are commonplace.
The dysfunction I’ve heard about on set is second only to that of the Fast and Furious movies. I mean, we mentioned a behind-the-scenes incident earlier this year that I didn’t want to go into detail about, and someone probably made it sound more dramatic than it actually was, but… yeah, I think, again, there’s a lot of testosterone and a lot of ego on that set. A lot of people who think they know the best path. In the end, only one person’s path matters, and that’s actually Robert Downey Jr.’s path.

Tensions between certain actors reportedly became so severe that scenes involving their characters had to be rewritten or cut to ease conflict, adding another layer of complexity to the production process.
Delays and Changes Impacting Avengers: Doomsday Release Schedule
The challenges during filming have contributed to significant delays. Avengers: Doomsday has been pushed back to a December 18, 2026 release date, with its sequel, Avengers: Secret Wars, following on December 17, 2027. Both films will see the return of the Russo brothers, Joe and Anthony, who have a strong history directing previous Marvel blockbusters.
Being able to create stories and explore characters within the Marvel Universe fulfilled a life-long dream of ours, and we discovered a powerful connection with audiences in each film that we made. We’re thrilled to collaborate once again with Kevin, Lou and the entire Marvel team to bring this epic adventure in storytelling to new and surprising places for both the fans and ourselves.
— Joe and Anthony Russo, Directors
