Anthony and Joe Russo are slated to helm the project after a few previous director switch-ups. The movie will mark their big return to the MCU after previously directing Captain America: The Winter Soldier (2014), Captain America: Civil War (2016), Avengers: Infinity War (2018), and Avengers: Endgame (2019).

Worries that he might not be "normal" are confirmed in Fantastic Four: First Steps when Galactus recognises that the boy can wield an unlimited energy known as the Power Cosmic (presumably because of the "cosmically compromised DNA" shared by both of his parents).

Robert Downey Jr. is already hard at work for his role as Doctor Doom in "Avengers: Doomsday!" In his latest Instagram post, he shared a “West Coast Avengers” comic book prominently showcasing the iconic villain. He also showed a tablet playing “Change of Scenery” by his son, Indio.
