During Marvel’s Hall H panel at San Diego Comic-Con, the studio announced that the Russo brothers have signed on to direct Avengers: Doomsday and Avengers: Secret Wars — the former of which will see Robert Downey Jr, return to the MCU as Doctor Doom. Doomsday is due out in May 2026, while Secret Wars will follow in May 2027.
Doctor Doom showing up just as the Fantastic Four are about to arrive makes it seem like Marvel’s been cooking up a plan to send its beleaguered Multiverse Saga off with a bang — one that’s probably going to be orchestrated by a guy who looks just like Iron Man.
