A New Era for Marvel’s Cinematic Universe

Marvel Studios has officially pivoted from its original Kang storyline to introduce Avengers: Doomsday, with the surprising announcement that Robert Downey Jr. will return to the MCU – not as Tony Stark, but as the formidable Victor von Doom/Doctor Doom. This revelation came during San Diego Comic-Con 2024, alongside the announcement that the Russo Brothers would direct the film.

Production and Release Details

Principal photography commenced in April 2025 at Pinewood Studios in England, bringing together an impressive ensemble cast. The film is now scheduled for release on December 18, 2026, with its sequel, Avengers: Secret Wars, following on December 17, 2027.

Unprecedented Character Convergence

The film promises to be Marvel’s most ambitious crossover yet, featuring the Avengers, Wakandans, Fantastic Four, and Thunderbolts (who serve as the government-sanctioned New Avengers), alongside the ‘original’ X-Men, all uniting to confront Doom. In a groundbreaking move, several actors from 20th Century Fox’s X-Men franchise, including Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden, will reprise their iconic roles.

Behind the Scenes

The production represents a significant investment for Disney, with the Russo Brothers and Downey reportedly earning $40 million and $50 million respectively per film, with potential bonuses based on box office performance that could double Downey’s earnings. The actor’s deal includes additional perks such as private jet travel, dedicated personal security, and multiple trailers on set.

Future Implications

According to Sam Wilson/Captain America actor Anthony Mackie, the film will feature a cliffhanger ending that ‘pushes the boundaries’ to set up the continuing MCU story, ominously noting that ‘everyone is expendable’. Kevin Feige has expressed that bringing the Fantastic Four and X-Men into the MCU fulfills a long-time dream, marking a significant milestone after 25 years of Marvel films.
