When Does Avengers: Doomsday Come Out?
Avengers: Doomsday is scheduled for release in cinemas on December 18, 2026. Directors Joe and Anthony Russo talked about how their leading man Robert was preparing to embrace the role of Doctor Doom before the cameras rolled.
“He’s completely absorbed by it. He’s totally focused,” Joe commented in May 2025, as cited by Variety. “He’s crafting backstory, devising wardrobe concepts… We were actually on the phone with him earlier this morning prior to arriving here, discussing it. He genuinely appreciates profoundly complex, well-rounded characters. He recognizes a genuine opportunity with this particular character.”
Robert’s reappearance in the Marvel Cinematic Universe after his character Iron Man met his end on-screen in Avengers: Endgame marks a milestone. The performer revealed the significant announcement at the 2024 San Diego Comic-Con, removing his mask on stage during Marvel’s segment.
