Avengers: Doomsday just announced Tom Hiddleston as part of its cast which means it's time for you to binge Loki to prep for the finale of the saga.

Rebecca Romijn, 52, will officially return as Mystique. She starred as the shapeshifter in “X-Men, X2: X-Men United,” “X-Men: The Last Stand” and “X-Men: First Class and Joan in The Punisher.”

Robert Downey Jr. returns to the MCU with other confirmed actors including stars Chris Hemsworth and Tom Hiddleston, 'X-Men' stars like Patrick Stewart and Ian McKellen, and a good chunk from the studio's 'Thunderbolts.

Fans who spent years watching the Marvel movies in order will remember a popular theory that Ant-Man could kill Thanos by entering his butt and growing. And Paul Rudd trying to explain this to his Death of a Unicorn co-star Jenna Ortega is seriously delightful.

The X-Men are going to play a big role in Avengers: Doomsday. We know that because a bunch of them, including Patrick Stewart and Ian McKellen, are confirmed for the gigantic MCU crossover. Their presence is fueling a lot of theorizing, and some fans think they may have spotted the Avengers vs. X-Men logo.

"Avengers: Doomsday" finds brothers Joe and Anthony Russo back in the directors chairs. They return to Marvel having helmed the Captain America films "Captain America: The Winter Soldier" and "Captain America: Civil War," as well as "Avengers: Infinity War" and "Avengers: Endgame."

Doomsday' cast was revealed, with Fantastic Four, X-Men and Thunderbolts stars, but few of the original stars.

SDCC 2024 announced that the Russo brothers will be directing both Avengers: Doomsday and Avengers: Secret Wars. The two are Marvel legends, since they helmed Avengers: Infinity War and Endgame, so it's welcomed news to see their return.

Robert Downey Jr was introduced into Marvel Cinematic Universe with 2008 film Iron Man, and since then he is synonymous with the superhero character.
