Avengers: Secret Wars Filming Update Just Reset Expectations for the MCU
The next Avengers one-two punch is locked: Doomsday is in post for a 2026 release, and sequel Secret Wars is set for 2027, with Joe and Anthony Russo directing both for Marvel Studios.
Marvel just nudged the giant machine forward again. The next Avengers sequel, Secret Wars, is lining up cameras for the summer, which should calm nerves about any big schedule wobble.
So what actually changed?
Per The Hollywood Reporter, Secret Wars is gearing up to film this coming summer. That meshes with a previous production listing spotted by Hollywood North Buzz that pegged a start in April 2026 and a wrap around September. April to September is basically spring into late summer, so those two bits of intel aren’t really fighting each other — they point to a similar window and scope.
Why that matters: Secret Wars is the direct follow-up to Avengers: Doomsday, and both are being steered by Joe and Anthony Russo. Doomsday is already in post-production and dated for 2026, and now Secret Wars appears to be on a parallel track production-wise. Translation: don’t panic about delays.
The trailer situation
Fans are still waiting on the first teaser for Avengers: Doomsday. It’s attached to Avatar: Fire and Ash, which hits theaters December 19, 2025. Whether Marvel drops that teaser online immediately is still a mystery, so if you want to see it day one, you might be doing it on the big screen.
What we know (and don’t) about the movies
Plot details for both Doomsday and Secret Wars are sealed up tight. Marvel hasn’t announced any casting for Secret Wars yet, but it’s a safe bet plenty of the Doomsday lineup will carry over.
