Robert Downey Jr. to Play Doctor Doom in Avengers: Doomsday

The Russo Brothers have officially confirmed that Robert Downey Jr. will begin filming his highly anticipated return to the MCU as Doctor Doom in Avengers: Doomsday. Fans were stunned when Marvel Studios announced that the iconic actor, who portrayed Tony Stark/Iron Man for over a decade, will now take on the mantle of one of Marvel’s greatest villains.

Filming Schedule Revealed

In an interview at New York Comic-Con, the Russo Brothers revealed that filming for Avengers: Doomsday will kick off in Spring 2025. This means Robert Downey Jr. will be back on set as the sinister Doctor Doom in just a few months. The directors also hinted at a confirmed start date but played coy on the specific location, jokingly keeping fans in suspense.

The script for Avengers: Doomsday is currently in the works, being crafted by longtime MCU writer Steve McFeely, who previously wrote Avengers: Infinity War and Endgame. The Russos shared that they are closely collaborating with McFeely and Christopher Markus, continuing their powerhouse creative partnership from previous Avengers films.

The Russos confirmed that Avengers: Doomsday and Avengers: Secret Wars will be filmed similarly to Infinity War and Endgame, though this time with a larger gap between shoots. While the two films are set to release just a year apart, the directors explained that the gap will be slightly longer to ensure each movie gets the attention it needs.

How Much Screen Time for Downey Jr.?

With Avengers: Doomsday set to be one of Marvel’s biggest films in 2026, Doctor Doom is expected to play a significant role. Downey Jr. will likely be heavily involved in filming, dedicating much of his schedule throughout 2025 and into 2026. Given that the two Avengers films are tied so closely together, Downey Jr. and other major cast members, such as Tom Holland, will have their hands full with back-to-back productions.

Aside from his role as Doctor Doom, Robert Downey Jr. will also be reprising his Tony Stark/Iron Man persona in two new attractions at Avengers Campus in Disneyland, ensuring his presence in the MCU continues to excite fans beyond the big screen.

With Avengers: Doomsday on the horizon, Robert Downey Jr.’s return as Doctor Doom marks a thrilling new chapter in the MCU’s ever-expanding saga. Fans can expect to see the actor dominate screens once again as the MCU hurtles toward one of its most anticipated showdowns.
