A new Avengers: Doomsday rumor is making the rounds, claiming that Marvel still doesn’t have a fully finished script for the movie.
According to YouTuber Doomcock, this goes back to information he says he received in May 2025 from Hollywood agent sources.
He claimed at the time there was “no script whatsoever” on set and that one of the Russo brothers was instead carrying around a notebook filled with story notes rather than a completed screenplay.
Doomcock points to daily rewrites
Doomcock brought the rumor back up after citing a social media post from Earth 616 claiming Avengers: Doomsday is being rewritten every single day on set (see below).
That claim points back to Kevin Feige saying last summer that there is daily “plus-ing” during filming, with actors and filmmakers continuing to reshape scenes as production progresses.
Doomcock argues that it might have worked for Avengers: Infinity War and Endgame, but says Doomsday is in a much different position, with Marvel needing the movie to deliver in a big way.
The rumor in part says: “Robert Downey Jr., Chris Evans, and the returning cast are actively reshaping scenes based on their deep knowledge of their characters. This isn’t a locked script it’s evolving every single day on set.”
Marvel continues to make changes
The rumor is getting attention because it aligns with the idea that Marvel is still adjusting the film well into production.
There has already been talk of reshoots and additional photography tied to Avengers: Doomsday, which only adds more fuel to the speculation.
Still, Doomcock’s claims remain unverified, and Marvel has not confirmed anything about the movie lacking a locked script.
It is known this does fit with the “Marvel way” of developing movies, as Marvel is known to change their scripts on the fly.
For now, it’s just another rumor surrounding what is easily one of Marvel’s biggest and most important upcoming movies.
Avengers: Doomsday release date
Avengers: Doomsday is currently set to hit theaters on December 18, 2026.
