Finally, the Loki TV series appeared to end with Loki sacrificing his freedom and his future to save a potentially infinite multiverse of parallel timelines, transforming his godly form into a cosmic structure that holds time together. And now, Marvel’s announcement suggests, he’ll be back in some capacity for Avengers: Doomsday.

Here are some of the biggest surprises announced in the "Avengers: Doomsday" cast so far, including Tom Hiddleston and more.

Marvel Studios has confirmed that Tom Hiddleston is set to reprise his role as Loki in Avengers: Doomsday . It was previously rumored that he could be one of the key elements to the story and the driving force behind the movie.

Marvel went with an elaborate way to announce — some of — the cast of the upcoming Avengers: Doomsday movie that is releasing in May 2026. Over a five-hour live stream and series of social posts, Marvel went chair-by-chair to list the long list of actors joining the first Avengers movie since Endgame.

Tom Hiddleston’s is among the few surprising-ish names announced on Wednesday for the MCU Phase 6 film Avengers: Doomsday, which is now officially in production and on track for a May 1, 2026 release.

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.

Avengers: Doomsday' has announced its star-studded cast, which includes some iconic superheroes (and shocking old ones) reprising their roles
