Overview

• James Marsden confirmed his Cyclops return and said the crossover "feels like something special," with Alan Cumming also back as Nightcrawler after initially thinking the offer was a prank.
• Marvel’s previously announced ensemble includes MCU mainstays alongside legacy X‑Men actors, with Joe and Anthony Russo directing and Robert Downey Jr. officially cast as Doctor Doom for a December 18, 2026 release.
• Unconfirmed reports from Daniel Richtman say principal photography, which began in April in the U.K., could wrap this week after several cast members finished their scenes, with a lengthy post‑production window likely to include reshoots.
• New rumor roundups suggest story elements such as a Doom "vendetta" against the Multiverse and an Avengers‑versus‑X‑Men clash, though Marvel has not validated any plot details.
• Deadpool and Wolverine are not on the official Doomsday cast lists, with Marvel‑related gaming projects recasting the characters (Neil Patrick Harris voices Deadpool in Deadpool VR), as insiders say some film cameos may be kept secret until release.
