‘Avengers: Secret Wars’ to Shoot in April 2026 — Will There Even Be A Script?

Marvel’s mega–two-part endgame machine keeps on going. The MCU has been struggling, and in a rather desperate move, decided to revert back to ‘Avengers’ movies — albeit without Iron Man, Captain America, and Hulk.

“Avengers: Doomsday” wrapped its marathon shoot this year, rolling cameras from April 28 until mid-September. Setting aside potential reshoots, the film now gets a luxurious 15-month post-production “break.”

Why so much breathing room? Easy — after finishing ‘Doomsday,’ the Russo brothers immediately pivot to its follow-up, “Avengers: Secret Wars.” Both films are rumored to become the costliest in Hollywood history, with budgets said to be in excess of 500M+ (although understandably, we cannot confirm at this time).

Hollywood North Buzz now claims “Secret Wars” will mirror the same April-through-September shoot next year in Vancouver. Another 15-month post window. Another VFX behemoth. More endless cameos — it’s all dialed to 11. Expect reshoots, and barely a finished script.

Oh, and did I mention the second phase of filming for ‘Doomsday’ — in other words, reshoots — kicks off in January 2026? There were probably some rewrites, maybe even a reshuffled cast list, since Marvel has been locking pieces of this puzzle together right up until the very last second.

The official synopsis includes Robert Downey Jr.’s return to Marvel — but this time as Doom himself. Not much else is known about the story being told here. Stephen McFeely and Michael Waldron are credited on the screenplay(s).

To give perspective: “Avengers: Endgame” cost $356M to make. ‘Doomsday’ already has $90M publicly accounted for — $40M for the Russos, $50M for Robert Downey Jr. With the avalanche of names reportedly attached, I’d be shocked if the final tally is under $400M. And that’s me being conservative.

Marvel continues to push the envelope: how many characters can they squeeze into a single movie before it collapses under its own weight?
