The Hugh Jackman uncertainty in a Patrick Stewart-led lineup

Hugh Jackman's return as Wolverine remains a major question mark for the production of Avengers: Doomsday. While the report notes that co-stars like Patrick Stewart and James Marsden are expected to play central roles, Jackman has received no official confirmation for the film. This creates a tension for fans, as the character was a cornerstone of the 2000s Fox films.

If Jackman does eventually appear, his version of Wolverine may not be the same character fans remember from the earlier franchise. According to the report, it is possible that the character might be held back for Avengers: Secret Wars to allow for a more significant role during the conclusion of the Multiverse Saga. This strategic delay would prevent the character from being spread too thin across multiple interconnected projects.

Ryan Reynolds’ Hall H teasing and the Deadpool connection

Ryan Reynolds has used public appearances to drop heavy hints regarding a potential role for Deadpool in the upcoming Marvel Studios film. During a 2026 Marvel Studios Hall H panel, Reynolds appeared in a unique grey version of the Deadpool suit to interact with guests. This appearance included light-hearted banter with Paul Rudd, who plays Ant-Man, and Robert Downey Jr., who is set to portray Doctor Doom.

The character of Deadpool is arguably one of the easiest to integrate into the current 616 reality. As the report highlights, Wade Wilson has already established connections with the TVA and even met with Happy Hogan regarding his status as a potential Avenger. While the Hall H interaction was comedic, it pointed toward a narrative path that makes his inclusion in Avengers: Doomsday highly plausible.

Why Colossus and Shawn Ashmore’s Iceman are sidelined

The current casting announcements for Avengers: Doomsday do not appear to include several beloved mutants like Colossus or Iceman. For Colossus, the character has a complicated history of portrayal, ranging from Daniel Cudmore in X-Men: Days of Future Past to the voice work of Stefan Kapicic in the Deadpool trilogy. The report suggests that without a clear casting direction, the character may not find a functional role in this specific film.

Similarly, Shawn Ashmore’s portrayal of Iceman, or Bobby Drake, is notably absent from the announced lineup. Iceman was a pivotal figure in the original X-Men trilogy and played a significant role in the Days of Future Past sequel . Despite his history and established connections to characters like Rogue, the character currently lacks a confirmed place in the upcoming Avengers assembly.

The transition from Kamala Khan to a full X-Men roster

Marvel Studios has been slowly introducing mutant elements into the MCU, starting with characters like Kamala Khan and Namor. This gradual approach serves as a bridge toward the massive shift that Avengers: Doomsday represents. With Jake Schreier confirmed to direct an upcoming X-Men movie, the studio is clearly building a foundation for a more permanent mutant presence in the shared universe.

The mystery of the returning Fox-era character versions

Several questions remain regarding how these legacy characters will fit into the new continuity. It is still unclear if the actors returning from the Fox era will play the exact same versions of their characters or if the MCU will introduce new iterations. Furthermore,the report leaves open the question of whether the absence of certain legends is a deliberate narrative choice or a result of ongoing casting negotiations.
