Robert Downey Jr is set to return to the Marvel Cinematic Universe but this time, as the menacing villain, Doctor Doom, in Avengers: Doomsday. The film will be released on December 18 this year.
The anticipation around Avengers: Doomsday has been sky-high since it was first announced. The excitement reached a fever pitch when it was revealed that Robert Downey Jr will make a comeback to the Marvel Cinematic Universe, but not as Iron Man aka Tony Stark.
While fans are waiting to catch a glimpse of his new Marvel avatar, Marvel Studios president Kevin Feige revealed how RDJ reacted when he was offered the vicious role. “His exact words were, ‘I played the best hero… I can play the best villain,'” Feige revealed at a recent event.

Meanwhile, the trailer for Avengers: Doomsday was unveiled at CinemaCon 2026. It hasn’t been released publicly yet, but as per reports, it electrified the crowd at ComicCon. The event was attended by Robert Downey Jr and Chris Evans.
According to reports from the event, the trailer opens with a glimpse of Doctor Doom, who appears to be orchestrating a multiversal invasion. It then cuts to Professor Xavier sensing an impending threat, followed by quick shots of several Marvel heroes, including Mr Fantastic, Bucky Barnes, Cyclops, Gambit, Shang-Chi, Mystique, Thor, and Captain America, among others.
