Warning: This post contains potential spoilers for Avengers: Doomsday.
It is no secret that the Marvel Cinematic Universe pivoted from its original vision for the Multiverse Saga at a very late stage. Kang the Conqueror was initially envisioned as the main villain of this chapter, and the X-Men weren't originally part of the narrative. However, in an unexpected twist, He Who Remains was dropped in favor of Doctor Doom, and fans were worried that there wasn't enough of a setup for the ruler of Latveria to take over the main stage. Fortunately, Marvel has done a lot of heavy lifting during these last two years.
Doctor Doom officially made his big (but brief) debut in the post-credits scene of The Fantastic Four: First Steps. This sequence was followed by numerous other setups, such as the New Avengers claiming there's a space crisis, Hulk being collected by the ruler of Latveria, Spider-Man suddenly disappearing from Earth, and the new villain in town trying to steal the Scarlet Witch's powers. Now, almost all pieces are set for Earth's Mightiest Heroes to assemble once more after a seven-year hiatus, but there are still a few missing links.
Aside from the 25 characters confirmed to be in Avengers: Doomsday, there will be additional appearances kept under wraps. However, speculation ran rampant about Wolverine and Deadpool's potential involvement when reports suggested Hugh Jackman and Ryan Reynolds helped write the screenplay for the next MCU ensemble movie, and now those suspicions have been confirmed.
Hugh Jackman confirms he and Ryan Reynolds contributed to writing the screenplay for Avengers: Doomsday
Variety recently published an Instagram post reporting on the story that Hugh Jackman and Ryan Reynolds are credited among the screenwriters of Avengers: Doomsday. Jackman then shared this post in his Instagram stories, confirming that he was involved in the production of the upcoming MCU film.
Now, it's worth clarifying that just because he was involved in the making of the MCU's upcoming film doesn't mean he will appear as Logan. That being said, the most likely scenario is that Hugh Jackman and Ryan Reynolds contributed by writing lines for their characters, Wolverine and Deadpool.
For months, it has been widely reported that the two mutants will play a key role in the opening sequence of Avengers: Doomsday. Apparently, their universe will be on a collision course with that of Tobey Maguire's Spider-Man, so both Wolverine and Deadpool will attempt to destroy the wall-crawler's Earth before the incursion happens. Rumor has it that the mutants will succeed in their mission, but Spider-Man and Wolverine will be left behind, seemingly dying in the process. However, they will both return as major figures in Avengers: Secret Wars.
It's also worth keeping in mind that Deadpool is present in a piece of official Avengers: Doomsday merch, which doubles down on the idea that both he and Logan will have a role to play in the MCU film.
Since the Multiverse Saga is coming to an end, Avengers: Doomsday and Avengers: Secret Wars are the last chances Marvel has to bring back some iconic heroes from different realities before the franchise goes back to having a "singular timeline," as revealed by Marvel Studios President Kevin Feige. As such, it comes as no surprise that Wolverine, Deadpool, and Tobey Maguire's Spider-Man will jump back into action one more time.
Logan and Deadpool are just the latest in a long list of recently "confirmed" appearances in Avengers: Doomsday. Marvel itself gave away that Mark Ruffalo's Hulk and Elizabeth Olsen's Scarlet Witch will be in the movie with the post-credits scenes of Avengers Endgame: Encore and VisionQuest. Moreover, Captain America himself, Anthony Mackie, revealed that Vision will also be back in the mix. Coupled with the trouble-making mutants and potentially even Spider-Man, it appears we'll be in for an incredibly ambitious film.
Avengers: Doomsday will be released on Dec. 18, 2026.
