A cultural moment born from Barbie and Oppenheimer’s simultaneous release
Marvel’s Avengers: Doomsday features a multi-universe lineup with Robert Downey Jr. returning as Doctor Doom. The film, slated for December 18, 2026, follows Doomsday’s clash with the Fantastic Four and the X-Men, as Comic-Con previews reveal. Gosling is cast as Ghost Rider, while Ian McKellen, Patrick Stewart and others reprise or join roles across a sprawling ensemble.
Warner Bros. faces losing Barbie sequel rights if negotiations with Margot Robbie, Ryan Gosling, and Greta Gerwig fail by December; Mattel would regain control, forcing a fresh creative slate if legacy elements cannot be used.
