The reboot will unify the MCU into a singular timeline, allowing Marvel to recast legacy characters like Iron Man and Captain America. Feige compared the process to other iconic franchises: “They’re looking for a new James Bond. David Corenswet is the new Superman, and he’s been incredible. That’s always how it works”.

Marvel is set to recast characters in its upcoming X-Men franchise and Tony Stark, a character that became synonymous with Robert Downey Jr in the Marvel Cinematic Universe.

Studio chief Kevin Feige said new cast of mutant characters will also be introduced in the upcoming X-Men film, set after 2027’s ‘Avengers: Secret Wars’

"As we as we kick off phase six with with 'Fantastic Four,' and as everybody knows it ends with 'Secret Wars,'" Feige said.

Many of the original X-Men actors are returning to their iconic roles, including Patrick Stewart (Charles Xavier), Ian McKellen (Magneto), Alan Cumming (Nightcrawler), Rebecca Romijn (Mystique), James Marsden (Cyclops), and Kelsey Grammer (Hank McCoy).

Marvel Studios boss Kevin Feige has explained how Avengers: Secret Wars will change the Marvel Cinematic Universe going forward. The next few years will see another huge two-part team-up, with Doomsday and then Secret Wars. But what will come after that?

Doomsday, due in 2026, will feature some Marvel figures who have been in the game even longer than Robert Downey Jr., as Iron Man. Patrick Stewart and Ian McKellen will return as Professor X and Magneto, having first played the roles for 2000’s X-Men movie.

Can Doctor Doom beat Thanos? It's an increasingly common question among Marvel fans, with Robert Downey, Jr.'s Doctor Doom set to inherit the title of the greatest enemy of the Avengers from Josh Brolin's Mad Titan, the almighty Thanos.

After the conclusion of Marvel's Secret Wars in 2027, the Marvel Cinematic Universe as we know it will be forever changed. "Reboot is a scary word,” Marvel boss Kevin Feige told Variety in a massive new interview.
