The multiverse is officially in motion as Avengers Doomsday filming continues across multiple locations, with Pedro Pascal reportedly completing his Reed Richards scenes while the Russo Brothers orchestrate Marvel’s most ambitious crossover since Endgame. The April 2025 production start has yielded fascinating behind-the-scenes insights into this May 2026 blockbuster.
Cast Chairs
The Avengers Doomsday filming process began with the Russo Brothers’ Instagram tease featuring a Victor Von Doom director’s chair, confirming Robert Downey Jr.’s shocking return as the iconic villain. Recent reports indicate Pascal has wrapped his Fantastic Four: The First Steps crossover scenes and is already negotiating his next project with Andor showrunner Tony Gilroy.
Marvel’s signature slow-reveal strategy showcased the ensemble cast through a five-hour livestream featuring director’s chairs labeled with cast names. This theatrical approach built anticipation while confirming returns from James Marsden, Channing Tatum, and other multiverse favorites alongside new additions.
Downey Jr.’s Villainous Transformation
The most intriguing aspect of Avengers Doomsday filming remains Downey Jr.’s transition from beloved Iron Man to Doctor Doom. Initially cast after Jonathan Majors’ removal as Kang, Downey Jr.’s casting was revealed at San Diego Comic-Con 2024. “The post-credit scene for Thunderbolts was filmed on the set of Doomsday,” providing early connective tissue between projects.
With a May 1, 2026 release date approaching, the Avengers Doomsday filming schedule appears ambitious yet manageable under the Russo Brothers’ experienced direction. Their previous Marvel successes with Infinity War and Endgame provide confidence in handling this multiverse-spanning narrative featuring both original X-Men and Fantastic Four characters.
