The ‘Avengers: Doomsday’ Script Had No Ending When Ebon Moss-Bachrach Read It

The Marvel Cinematic Universe is gearing up for its most ambitious crossover in years, and the actor set to anchor a major part of it has offered a surprisingly candid window into its creation. Ebon Moss-Bachrach, widely celebrated for his Emmy-winning role as Richie in ‘The Bear’, made his MCU superhero debut as Ben Grimm in ‘The Fantastic Four: First Steps’, a film that introduced Marvel’s First Family to the franchise in a retro-futuristic 1960s setting.

‘Avengers: Doomsday‘ has had an unusually turbulent path to screens, originally scheduled for May 2025 before being delayed twice, with the film now set to arrive on December 18, 2026, to allow more time for production to be completed. That reshuffling was the result of a major creative pivot following Jonathan Majors’ departure from the Kang storyline, a rebranding of the entire project, and the introduction of Robert Downey Jr. as the new central villain, Doctor Doom, alongside industry-wide disruptions caused by the 2023 Writers Guild of America and SAG-AFTRA strikes.

Against that backdrop, recent comments from Moss-Bachrach about the ‘Avengers: Doomsday’ script are drawing significant attention online. The actor confirmed that he had obtained and read a full draft of the screenplay, but the version he encountered appears to have been far from complete. Moss-Bachrach said plainly: “I did read a full script, but those scripts change quite a bit. It probably didn’t have a full third act. I don’t think it had an ending. I don’t think anyone gets to see that stuff.”

This is not the first time the actor has described script fluidity on a Marvel production. When speaking to Variety about ‘The Fantastic Four: First Steps’, Moss-Bachrach acknowledged that the screenplay was not finalized when the cast began rehearsals, saying the production became “sort of workshopping the movie in a way.” For a project as interconnected and monumental as a multi-universe Avengers film, the absence of a finished third act during active production is the kind of detail that tends to stick in the minds of anxious fans.

His co-stars from ‘The Fantastic Four: First Steps’ have each offered their own takes on the ‘Doomsday’ experience with a mixture of awe and good humor. In a conversation with Collider, Joseph Quinn described the screenplay as “definitely ambitious,” reflecting on how difficult it must be to write for that many characters and at that scale, while Moss-Bachrach noted that he found the script “very confusing,” saying there were so many code names that he “could never figure out who was who.” Vanessa Kirby compared the whole process to assembling an extraordinarily intricate recipe, one where the studio has to figure out exactly which flavors belong together and in what order.

The film brings together heroes from three distinct universes, including the Avengers, Wakandans, and New Avengers from Earth-616, the Fantastic Four from Earth-828, and the original X-Men from a separate universe, with filming having taken place at Pinewood Studios in England. The confirmed cast alone runs to more than two dozen names, including Patrick Stewart, Ian McKellen, James Marsden, Pedro Pascal, Chris Evans, and Robert Downey Jr., among many others.

Moss-Bachrach himself has remained enthusiastic about the project on a broader level, describing ‘Avengers: Doomsday’ to BBC News using four pointed words: “Epic. Tragic. Intergalactic. Starry.”

Early box office tracking has reportedly been strong, with predictions pointing to ‘Doomsday’ being among the highest-grossing films of the year, and the response to promotional material at CinemaCon was described as overwhelming by those in attendance.

Whether the finished film can deliver on all of that hype, knowing it was being shaped in real time from a script without a third act, is something only December will answer, so it’s worth asking whether you believe a movie this massive can still stick the landing when even Ben Grimm himself admits he never got to read the ending.
