Robert Downey Jr. returns as MCU gears up for ‘Avengers: Doomsday’ production

The Russo Brothers are set to direct the pivotal film featuring the debut of Victor von Doom in the Avengers: Doomsday storyline.

Marvel Studios is officially moving into high gear for what is being described as its most ambitious crossover since Endgame. According to sources close to the production, filming for Avengers: Doomsday is slated to begin this March in the United Kingdom, marking a massive shift in the Marvel Cinematic Universe (MCU) trajectory.

The production has recently expanded its scope, with veteran cinematographer Newton Thomas Sigel joining the crew. The narrative pivot from the "Kang" storyline to Victor von Doom has necessitated significant script rewrites by Stephen McFeely. Inside sources suggest that the "Doomsday" subtitle isn't just for show; the plot reportedly involves a "collision of realities" that will serve as a direct lead-in to Secret Wars. Robert Downey Jr.’s involvement is said to be more than a mere cameo, with the actor reportedly undergoing extensive prosthetic tests to perfect the iconic mask-clad look of the Latverian dictator.
