At the 2024 San Diego Comic-Con, Marvel Studios announced that Robert Downey Jr. will return to the MCU as Doctor Doom in the upcoming films 'Avengers: Doomsday' and 'Avengers: Secret Wars,' marking a significant comeback after his character's death in 'Endgame.' The Russo Brothers, who previously directed major MCU titles, will also return to helm these films, replacing Destin Daniel Cretton. Zack Snyder expressed his enthusiasm for the Russo's return, stating they have the talent to deliver something amazing and that the change is needed in the franchise. Downey shared that his decision to return was influenced by ongoing relationships with Marvel leadership and a desire to contribute to Disney parks' experiences. Meanwhile, debates are ongoing regarding Sony's interest in bringing back Tobey Maguire and Andrew Garfield for a new Spider-Man film, which may conflict with Marvel Studios' plans for a more grounded story. Fan reactions suggest a preference for a standalone Spider-Man narrative rather than additional multiverse team-ups.
