When does Avengers: Secret Wars release?
Avengers: Secret Wars opens on 17 December 2027, exactly one year after Doomsday. The Russos are filming both movies in one long production block, which is why casting news for the two blurs together. Full dates sit on our MCU release calendar.
What is Avengers: Secret Wars about?
Marvel has not released an official synopsis, but the shape is clear from the comics and from how Doomsday is set up: Doctor Doom’s multiversal endgame collapses realities into a single patchwork world, Battleworld, and the surviving heroes have to put the multiverse back together. Expect it to double as the MCU’s reset button for the next phase.
