Joe and Anthony Russo are not getting a break between their two back-to-back Marvel epics — and by their own admission, the transition is happening fast enough to cause genuine anxiety.
Speaking exclusively with Collider’s Steve Weintraub at San Diego Comic-Con 2026 following Marvel Studios’ Hall H panel, the Russo Brothers confirmed that while Avengers: Doomsday remains their immediate priority, preparations for Avengers: Secret Wars are already well underway behind the scenes.

Where Doomsday Currently Stands
Anthony Russo described the current state of Doomsday post-production as all-consuming. The directors are deep in the final stretch — working through the film’s musical score with legendary composer Alan Silvestri, refining the sound mix, and attending to the accumulated “grace notes” that define a finished Marvel film. Russo teased that what Silvestri has created specifically for Doctor Doom is something audiences will not be prepared for, though he stopped well short of providing specifics.
At the same time, both directors are simultaneously laying the groundwork for what comes next.
Secret Wars Filming Is Coming Very Soon
When Weintraub asked directly whether Anthony Russo was ready to reveal when Avengers: Secret Wars would begin filming, the director’s answer was candid, brief, and immediately quotable.
“Soon. So soon it makes us sweat a little bit.”
The Russo Brothers have yet to reveal an official production start date for Secret Wars, and Marvel Studios has not made any formal announcement. But the directors’ language — and the visible tension behind it — makes clear that the gap between completing one film and beginning the next is remarkably compressed. The scheduling reality is that Secret Wars is set for a December 17, 2027 theatrical release, meaning the timeline leaves very little room between the finishing of Doomsday and the launch of its sequel production.
What Secret Wars Needs to Deliver
Avengers: Secret Wars represents the conclusion of the MCU’s Multiverse Saga — the culmination of years of storytelling threads that have been woven across dozens of films and series. Doomsday is expected to set the stage for that finale, meaning Secret Wars arrives with an enormous amount of narrative expectation already built in.
The confirmed cast so far includes Robert Downey Jr. as Victor Von Doom/Doctor Doom, Pedro Pascal as Reed Richards/Mr. Fantastic, Vanessa Kirby as Sue Storm/Invisible Woman, and Ebon Moss-Bachrach as Ben Grimm/Thing, among many others expected to return from across the MCU.
For the Russo Brothers, who are simultaneously finishing one of the biggest films ever made while preparing to immediately begin another, the next twelve months are going to be unlike anything they have experienced before. As Anthony Russo put it — complicated, but thrilling.
Avengers: Doomsday opens in theaters on December 18, 2026. Avengers: Secret Wars follows on December 17, 2026.
