Warning: This post contains spoilers for the finale of VisionQuest and potential spoilers for Avengers: Doomsday.
On March 26, 2025, Marvel Studios hosted a livestream where it revealed over 25 characters set to appear in its most ambitious project to date, Avengers: Doomsday. After that day, fans continuously theorized that a second announcement could be on the way to unveil the rest of the film's cast. And although this didn't end up happening, the last few months have been huge for the Marvel Cinematic Universe as a whole. After all, many different heroes have been indirectly confirmed to be in the upcoming ensemble film in a number of different ways.
The post-credits scenes of Avengers Endgame: Encore and VisionQuest revealed that both the Hulk and the Scarlet Witch will be back in action once more... except they may be on the wrong side of history this time around. Furthermore, Captain America himself, Anthony Mackie, accidentally let slip that Vision will also join Earth's Mightiest Heroes. As if that wasn't enough, leaked pictures of one of the Latverian witches all but confirmed that Doctor Strange will have a role in the film as well.
In a way, we did get a second cast announcement due to the sheer number of character reveals that have come our way recently. So, to keep the streak going, two more heroes may have accidentally been confirmed to join Earth's Mightiest Heroes in their upcoming adventure.
Hugh Jackman and Ryan Reynolds are credited as writers of Avengers: Doomsday, suggesting Wolverine and Deadpool are involved
The official Avengers: Doomsday page in the Writers Guild of America West has been updated to add additional writing credits to Hugh Jackman, Ryan Reynolds, and Destin Daniel Cretton. The latter is the director behind multiple acclaimed MCU projects such as Shang-Chi and the Legend of the Ten Rings, Wonder Man, and Spider-Man: Brand New Day. As such, it comes as no surprise that he also worked on Marvel's most ambitious film to date. But what does it mean for the two Marvel actors to be involved?
Ryan Reynolds has co-written the screenplay for Deadpool 2 and Deadpool & Wolverine, and he is also writing a new Deadpool project. As such, it isn't far-fetched to assume he wrote some of the Merc with a Mouth's dialogue for Avengers: Doomsday. A similar scenario could be in store for Hugh Jackman, who could've also written some lines for Wolverine.
Of course, it's also worth considering the possibility that Destin Daniel Cretton, Hugh Jackman, and Ryan Reynolds were credited because they worked on the script for Avengers: The Kang Dynasty instead, which was eventually reworked into Avengers: Doomsday. After all, this scenario is exactly why Jeff Loveness is still credited on Marvel's upcoming movie, despite not being actively involved in the production of Doomsday.
If Reynolds and Jackman were involved in the writing of Avengers: The Kang Dynasty, it is entirely possible their scenes as Deadpool and Wolverine were ultimately scrapped for Avengers: Doomsday. That being said, industry insider Cryptic HD QUALITY revealed on Nov. 4 that the two Marvel actors would be credited as writers (which turned out to be the case), and when the scooper was asked what the news means, they simply replied, "It means Tobey is cooked."
This is a nod to the multiple leaked pictures, rumors, and reports that indicate Tobey Maguire's Spider-Man will fight Hugh Jackman's Wolverine and Ryan Reynolds' Deadpool in the opening sequence of Avengers: Doomsday. The three heroes will be involved in a multiversal incursion that will serve not only to set the tone for Marvel's upcoming movie, but also to explain that the X-Men universe is destroying any parallel Earth that's about to clash with theirs.
It's also worth keeping in mind that Deadpool is present in a piece of official Avengers: Doomsday merch as well, which would confirm the character's appearance. Moreover, all signs indicate that Hugh Jackman will be back in action as Logan, too, and we can't wait to see how it all pans out.
Avengers: Doomsday will be released on Dec. 18, 2026.
