Reports circulating this week that filming on Avengers: Secret Wars may slip into early 2027 have reignited concerns among Marvel Cinematic Universe fans about whether the studio can still deliver its sprawling Multiverse Saga finale by its current December 17, 2027 release date. Serial MCU tipsters including Daniel Richtman, Alex Perez, and Apocalyptic Horseman appear to have independently verified that principal photography on the film could now begin in January 2027, a shift from an earlier schedule that had set production to start last month.
The staggered reporting across multiple well-known insiders lends weight to the claim, though it is worth emphasizing that Marvel has not issued any official update regarding its production timeline. The studio may ultimately have no need to do so if the revised shooting schedule does not threaten the film’s planned launch window. That uncertainty, however, has prompted widespread speculation online about whether the movie can still be completed on time.
Fan Reaction and Speculation
The discussion has been lively across Reddit, where fans have weighed in with a range of perspectives on what a delay might mean for Marvel’s broader slate. One viewer noted that pushing production back could give the cast more time to promote the upcoming film Avengers: Doomsday during the winter months.
“Gives the cast time to promote Doomsday during this winter. I’m not in a rush for Ghost Rider so as long as we get X-Men and BP3 still in 2028, I’m fine with this.”

Others took a more cautious approach, suggesting that the studio may be deliberately pacing its plans based on how Doomsday is received. One commenter argued that a significant amount rests on that film’s performance and that Marvel could recalibrate its second-act films depending on critical and audience reception.
“A lot is riding on Doomsday. They’re probably waiting to see how it’s received before committing to anything. If Doomsday gets a bad critical and/or audience reception then that’ll drastically change what they’d do in its second act film.”

The impatience was echoed by another fan who pointed out that Secret Wars was first announced back in 2022, expressing frustration at the length of time fans have already waited for the culmination of the saga.
A Tight Production Timeline
To understand the stakes, it helps to look at how much work Marvel has already completed. Principal photography on Avengers: Doomsday ran five months from April through September 2025, with additional material believed to have been shot recently ahead of that film’s December launch. In practical terms, this means Marvel has had just over a year to process the bulk of its footage in post-production.
A useful comparison comes from Spider-Man: Brand New Day, which was filmed between August and December 2025 for a July 2026 release. That represents a considerably tighter turnaround than what fans now believe Secret Wars may require, particularly given the enormous story scope and sprawling cast list that define the Avengers films. Brand New Day is arguably a more straightforward project by comparison.
Much remains unclear about the situation, including the exact date production might begin and whether Marvel has already captured footage it could incorporate into Secret Wars while shooting Doomsday. This technique was notably used for both Avengers: Infinity War and Endgame, allowing the studio to work on multiple films simultaneously in post-production.
Looking Ahead
A delay would not come without consequences. Should Secret Wars slip into 2028, it would likely ripple through Marvel’s slate, impacting three subsequent projects already scheduled for that year: X-Men, Ghost Rider, and Black Panther 3. The studio faces a genuine trade-off between protecting the quality of its biggest film and maintaining momentum across its broader lineup.
“Secret Wars was announced in 2022 for Christs sake.”

As the situation continues to develop, fans and industry watchers alike will be watching closely to see whether Marvel confirms a revised production schedule or quietly proceeds toward its December 2027 target. Until then, the studio’s plans for its most anticipated film remain officially unconfirmed.
