- Quick Answer: The Writers Guild of America credited Ryan Reynolds and Hugh Jackman with "Additional Literary Material" (not on-screen) on Avengers: Doomsday, leaning on a potential Deadpool and Wolverine return.
Marvel Studios has fought tooth and nail to keep the full roster of Avengers: Doomsday under wraps, even after unveiling the initial major cast lineup.
However, an official update from the WGA may have just given away two of the movie's biggest secrets, revealing two of the top fan-favorite multiverse stars who contributed directly to the script.
Writers Guild of America (WGA) Drops Surprising Hint for Avengers: Doomsday Fans
While Stephen McFeely and Michael Waldron hold the main credit title for penning the script for Avengers: Doomsday, an updated entry on the official Writers Guild of America website directory revealed several contributors under the "Additional Literary Material" banner, most notably Ryan Reynolds and Hugh Jackman.
According to WGA's rulebook, this credit is typically awarded when any writer or performer contributes specific dialogue or script revisions during production that renders WGA-covered writing services on the project, but falls short of the 33% threshold to receive an official on-screen writing credit.
Considering that Reynolds famously shapes Wade Wilson's meta-humor on set through rewrites and ad-libs alongside Jackman to keep their banter sharp, their dual credit indicates they stepped onto the Doomsday set to cut into their characters' specific interactions firsthand.
Neither Reynolds nor Jackman was included in Marvel's initial chair-reveal cast announcement, which seemingly means their cameo or supporting role was intentionally held back as a theatrical surprise.
What Fans Can Likely Expect From Deadpool and Wolverine's Return
With Avengers: Doomsday assembling the Avengers, the Fantastic Four, and the classic Fox-era X-Men, bringing Wade Wilson and Logan into the fold could serve as key bridges connecting the X-Men to the main MCU timeline as incursions collide.
With Patrick Stewart (Professor X), Ian McKellen (Magneto), James Marsden (Cyclops), and Channing Tatum (Gambit) confirmed for Doomsday, and Robert Downey Jr.'s casting as Victor von Doom, Wade Wilson is likely guaranteed to break the fourth wall and address the elephant in the room as part of his comedic relief routine.
Even if their screen time in Doomsday may be limited to a third-act sequence or post-credits setup, their appearance would cement Deadpool and Wolverine as major players heading into the culmination of the Multiverse Saga.
In the meantime, fans can wait to confirm whether Deadpool & Wolverine will return to the MCU in Avengers: Doomsday, premiering on December 18, 2026.
