a grand promotional effort for “Avengers: Doomsday” in mid-December and early January, unveiling four brief teaser trailers for the eagerly awaited Marvel Cinematic Universe (MCU) crossover that highlighted several key members of the Avengers team. Nevertheless, Marvel did not issue a complete “Avengers: Doomsday” trailer at that time, nor did it display Robert Downey Jr.’s Doctor Doom in the clips. Instead, the studio utilized the theatrical release of “Avatar: Fire and Ash” to build excitement for the forthcoming “Avengers” film.
Jump to April 16, and Marvel has at last revealed Doctor Doom. The inaugural “Avengers: Doomsday” trailer debuted at CinemaCon 2026. Marvel’s presentation at CinemaCon included Marvel president Kevin Feige, “Doomsday” directors Anthony and Joe Russo, and two of the most significant and cherished MCU actors: Robert Downey Jr. and Chris Evans. The duo has portrayed Tony Stark/Iron Man and Steve Rogers/Captain America in numerous MCU films, encompassing all “Avengers” entries released thus far.
Following their conflict on opposing sides in “Captain America: Civil War,” they will find themselves at odds again in “Doomsday.” This time, Steve Rogers and the Avengers must confront Victor von Doom, portrayed by RDJ. The two actors also shared a lighthearted moment during the event, as Evans remarked that he has a dislike for Downey Jr.’s Doctor Doom.
