Marvel continues to roll out teaser trailers for its upcoming film, “Avengers: Doomsday,” and on Tuesday, the latest trailer was officially released online, confirming the return of the X-Men.

In March 2025, the internet bore witness to Marvel Studios announcing the cast of "Avengers: Doomsday" with a comically long livestream of chairs with cast members' names on them.

The third teaser trailer for Avengers: Doomsday focuses on the X-Men, promising the return of Patrick Stewart as Professor X, Ian McKellen as Magneto, and James Marsden as Cyclops.
