Marvel Studios just dropped a five-hour livestream to not only celebrate the official start of production on Avengers: Doomsday, but to casually (read: dramatically) unveil one of the biggest ensemble casts they’ve ever assembled.

The concept was simple but genius: reveal the actors one by one by showing their names slowly appearing on the backs of classic director’s chairs. And of course, the final name to appear? Robert Downey Jr. Sitting in his new seat of power, he officially completed the tagline tease we’ve been hearing for months: “It all leads to Doom.”

Here’s everyone confirmed so far — in alphabetical order, because otherwise it gets chaotic fast:

Alan Cumming – Kurt Wagner / Nightcrawler | X-Men Universe
Anthony Mackie – Sam Wilson / Captain America | MCU – Avengers
Channing Tatum – Remy LeBeau / Gambit | X-Men Universe
Chris Hemsworth – Thor | MCU – Avengers
Danny Ramirez – Joaquin Torres / Falcon | MCU – Avengers

Avengers: Doomsday lands in cinemas on May 1, 2026 — and based on this cast? It’s going to be absolutely wild.
