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.

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

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?

Marvel Studios is planning big changes. A new X-Men movie is coming. It will reset the Marvel Cinematic Universe after 'Avengers: Secret Wars' in 2027. Kevin Feige says new actors will play X-Men. Iron Man and Captain America may also be recast.

Overall, The Fantastic Four: First Steps is Marvel's most unique movie in years (Shakman nailed it with Earth-828's '60s aesthetic), but it's too uneven to crown a “masterpiece” by their standards. Still, expect all of the “Marvel is back” quotes plastered onto trailers after opening weekend.

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.

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’

Kevin Feige addresses what's next for the Marvel Cinematic Universe, and it includes recasting the X-Men and a reset of the MCU.
