Robert Downey Jr. just gave Marvel fans something to get excited about a behind-the-scenes photo from the set of Avengers:Doomsday. The image, shared on social media, shows Downey casually reading Jeremy Renner’s book outside his trailer, but it’s what’s on his face that really got people talking.
In the photo, Downey is wearing facial motion capture dots, a clear sign that his role will involve some serious CGI likely for Doctor Doom’s iconic metal mask. That’s right, Downey Jr. isn’t returning as Iron Man this time; he’s stepping into the role of one of Marvel’s most complex villains, Victor Von Doom.
The fan response has been immediate and passionate. Many are curious about how the mask will look, with some speculating it might borrow elements from Iron Man’s design a mix of sleek tech and intimidating presence. Others are simply thrilled to see Downey Jr. back in the MCU, even if he’s playing the bad guy this time around.
Avengers: Doomsday is shaping up to be a massive event. Directed by the Russo brothers, the film will feature familiar heroes like Thor, Ant-Man , and Loki , alongside newcomers to the MCU, including Pedro Pascal as Mr. Fantastic and Vanessa Kirby as Invisible Woman.
Downey’s return as Doctor Doom adds another layer of hype. It’s a bold move for Marvel — taking one of its most beloved heroes and casting him as one of its most feared villains. But if anyone can pull it off, it’s Robert Downey Jr.
Avengers: Doomsday hits theaters on May 1, 2026.
