"Avengers: Secret Wars" Filming Timeline Gets Huge Update From The Russo Brothers

The Russo brothers are ferociously juggling two of Marvel’s biggest projects, “Avengers: Doomsday” and “Avengers: Secret Wars,” at once. The transition from one to the other is arriving sooner than many fans expected. The Russo brothers are still working on “Doomsday,” but they have begun planning for “Secret Wars.”

Joe and Anthony Russo told Collider’s Steve Weintraub at San Diego Comic-Con that while they remain focused on finishing “Avengers: Doomsday,” they have already begun preparing for “Avengers: Secret Wars” behind the scenes. Anthony Russo said the pair are in the final stages of post‑production on “Doomsday,” working through music, sound mixing, and other finishing touches with composer Alan Silvestri, and simultaneously laying groundwork for the next crossover.

He said on Collider, “We’re deep into finishing the movie, into finishing Doomsday. All of the grace notes, the music, working with Alan Silvestri, sound mix, creating Alan’s incredible original music. Wait until you experience what he’s cooked up for Doom. That, and then we’re prepping. We’re prepping Secret Wars. So, it’s a complicated time in our lives, but thrilling.” Anthony Russo stopped short of giving a firm start date for “Avengers: Secret Wars,” but he made clear that the gap between the two productions will be short.

When asked whether he could reveal when “Secret Wars” would begin filming, he indicated the start is imminent, saying it will happen so soon it makes them sweat a little. The studio has not issued an official announcement, but the Russos’ comments suggest cameras could roll in the near future. The timing aligns with Marvel’s release schedule. “Avengers: Doomsday” is set to premiere on Dec. 18, 2026, and “Avengers: Secret Wars” is slated for release on Dec. 17, 2027. Given that calendar, a quick turnaround between the two films would be consistent with Marvel’s plan to close the Multiverse Saga with a major crossover event.

The brothers described a period of intense, overlapping work. For “Doomsday,” they are in post‑production, focusing on the final sound mix and the film’s score. They praised Silvestri’s contributions and urged audiences to wait for the composer’s work on the film. At the same time, they are preparing for “Secret Wars,” a term that in film production typically covers everything from script refinement and casting logistics to scheduling and early design work. Anthony Russo framed the current stretch as complicated but exhilarating.

The pair are balancing the meticulous, detail‑oriented work of finishing one tentpole film while beginning the logistical and creative planning for another that is expected to be even larger in scope. A few months ago, Chris Evans confirmed that he will once again reprise his role as Steve Rogers in “Avengers: Secret Wars.” Instagram user @comicconmomsi posted Evans confirming his role in “Secret Wars.” Evans to the user in a video, “I can tell you that I start work on the next one in a couple of months. I can’t tell you how much I’m in the next one, but I’m in it.”

Stakes And Expectations of “Avengers: Secret Wars”

Marvel has kept most plot details under wraps, but the studio has positioned Secret Wars as the payoff to years of storytelling across the MCU and the Multiverse Saga. The Russos’ involvement and their comments about an accelerated schedule underscore the scale of the undertaking: “Secret Wars” is being built as a culmination of legacy characters and multiversal heroes converging in a single event. While the filmmakers did not disclose story specifics or production dates beyond their general timeline, their remarks reinforce the sense that Marvel is moving quickly to bring the franchise to its next major chapter.

The suggestion that filming will begin soon adds momentum to fan expectations and industry speculation about how the studio will marshal its resources to deliver a year‑to‑year sequel. The Russos’ description of their workload conveyed both pride and fatigue. Finishing a film like “Doomsday” requires attention to small creative choices; the making of music and sound that can change how audiences experience a scene while prepping a film of this magnitude demands early decisions that will ripple through casting, effects, and marketing.

The brothers acknowledged the strain of managing both but framed it as a thrilling professional challenge. For Marvel and its audience, the compressed timeline signals confidence that the studio can sustain a rapid production cadence without sacrificing the scale or ambition of its flagship titles. For the Russos, it means little time to catch their breath between two of the most consequential films in the MCU’s current slate. “Avengers: Secret Wars” will be the sixth “Avengers” film in the MCU.
