While we know when the movie will be released, there are still a few other key details that are still unknown. The cast for the film was not announced by the full panel. It’s also unclear whether John Krasinski, who appeared as a multiverse version of Mister Fantastic in “Doctor Strange in Madness’s Multiverse,” will reprise his role for this new film.
Another big unanswered question on the San Diego Comic-Con panel is who will direct “Fantastic Four.” In December 2020, “Spider-Man: No Way Home” director Jon Watts was announced to lead the family’s return to the big screen. This past April, however, it was announced that he had amicably stepped down from the director’s chair, with his decision reportedly being made to halt superhero movies (after all, he directed all three “Spider-Man” movies in the MCU return-return). For now, seats are probably still vacant, although it’s likely that Watts’ replacement, as well as the actors playing the four main heroes, will be announced before or during the D23 expo this September.
