The highly anticipated sequel to Marvel Studios’ upcoming film may be heading toward yet another setback, with multiple prominent MCU leakers reporting that principal photography has been pushed back from October 2026 to January 2027. According to well-known industry insiders Daniel Richtman, Alex P., and Apocalyptic Horseman, the delay would jeopardize the movie’s current December 17, 2027 theatrical window, though Disney has not issued an official comment confirming the change.
The reporting began with Richtman, who initially claimed that filming had been postponed to November before revising his claim further out to January. Both Alex P. and Apocalyptic Horseman independently corroborated the later timeline, lending credibility to the report. If confirmed, this would mark another disruption for a production already burdened by Marvel’s recent history of shifting release dates.
A History of Shifting Schedules
The upcoming film was originally slated to begin filming in mid-2026 before Disney moved that target back to August and then later into the year. The sequel is currently planned for a December 17, 2027 release, landing roughly a year after its predecessor’s December 18, 2026 debut. While it remains possible for the production to still hit its original release date, observers note that the heavy post-production and CGI work these blockbuster films demand could make adhering to that timeline difficult.
To put the compressed schedule into perspective, filming for the predecessor ran from April to September 2025, meaning the shoot wrapped approximately 15 months before its theatrical release. If this new installment follows a similar pattern and begins in January 2027, it would finish principal photography around June 2027—leaving only about six months before its debut.
A Compressed but Not Unprecedented Timeline
This compressed schedule is not without precedent within the studio’s recent output. The upcoming Fantastic Four film began filming in August 2025 and wrapped in December 2025, roughly seven months before its July 27, 2026 debut. A similar timeline characterized another recent release, suggesting that while the expected scope of this massive crossover event would make such a schedule challenging, Disney appears determined to avoid postponing the release once again.
The film and its predecessor were previously delayed, moving from their original May 1, 2026 and May 27, 2027 slots to December 2026 and 2027. That shift already altered the studio’s carefully constructed roadmap for its multiverse saga.

The Russo Brothers began directing with an incomplete script, saying they learned to play off their actors when they were the showrunners for Community, reflecting a more haphazard planning approach than the franchise’s previous duology of Infinity War and Endgame.

The future of the Marvel Cinematic Universe remains heavily dependent on these upcoming films. While Spider-Man: Brand New Day delivered a phenomenal box office performance, industry analysts suggest that the next two Avengers movies will likely carry even greater weight for the franchise’s long-term trajectory.
Why Is Secret Wars Reportedly Being Delayed?
The most plausible explanation for the reported delay is that Disney may be waiting to gauge box office and fan response before committing resources to this massive production. The two films appear to have been planned more haphazardly than the franchise’s last duology, with directors facing incomplete scripts during early development.
This cautious approach stands in contrast to the earlier strategy behind Infinity War and Endgame, which benefited from years of careful planning across a shared narrative. As fans await official confirmation from Disney, the entertainment community watches closely to see whether this reported filming delay will translate into another release postponement or remain just another production adjustment.
Looking Ahead
Until Disney issues an official statement, the January 2027 filming date remains unconfirmed. The studio faces a delicate balancing act: giving its directors adequate preparation time while maintaining enough buffer for the extensive visual effects work that these films require. Whether the production can honor its December 17, 2027 release window will depend heavily on how quickly principal photography proceeds once it begins.
Fans and industry watchers alike remain hopeful that Marvel can avoid further delays as it approaches this pivotal chapter in its cinematic universe. The outcome of these upcoming productions may well determine the direction of the franchise for years to come, making every scheduling decision a matter of significant interest to audiences worldwide.
