Deadpool and Wolverine Stars Receive Surprise Credits in Avengers: Doomsday

Doctor Doom arrives in a little over a month, and Disney has published a rundown of the characters central to the story in Avengers: Doomsday.

The film will feature original MCU Avengers Steve Rogers and Thor, as well as Sam Wilson, the new Captain America, Ant-Man, and Shang-Chi. The Fantastic Four will also have a prominent role. Victor von Doom originated in the group’s comics. The New Avengers from Thunderbolts will appear alongside Wakandans like Shuri.

Trailers have shown that the X-Men will have a prominent place in Doomsday, but they won’t be the versions appearing in the MCU’s upcoming X-Men film. Instead, Doomsday will reunite mutants from the early-2000s 20th Century Fox X-Men trilogy. Patrick Stewart will appear in his final role as Professor X, Ian McKellen will return as Magneto, and James Marsden will play Cyclops.

Who else may make cameos in Doomsday?

Beyond those confirmed returns, writing credits spotted by DiscussingFilm hint that two more mutants may appear. The Writers Guild of America West’s credits page for Avengers: Doomsday lists Ryan Reynolds and Hugh Jackman for “Additional Literary Material: (not on-screen).” The descriptor applies to writers who contribute to part of a script, such as intermediate drafts or punch-ups, but did not write most of the final screenplay.

Reynolds’ existing WGA credits are for Deadpool 2 and Deadpool & Wolverine, both of which he co-wrote and starred in as Deadpool. Jackman has no existing WGA writing credits, but he is known for playing Wolverine.

The writing credits do not confirm that either actor will appear in Doomsday. Both have made promotional appearances for the film, including at D23, which some have taken as evidence that they will be in it. Reynolds also fueled speculation last year when he posted an Avengers logo covered in graffiti on Instagram.

The cameos would fit the story. The original Wolverine from the 20th Century Fox films died in Logan, but Deadpool befriended an alternate-universe version of him in Deadpool & Wolverine. Avengers: Doomsday appears to be a send-off to the Fox X-Men movies, in which Wolverine was the most prominently featured character.

Avengers: Doomsday arrives in theaters on Dec. 18, 2026.
