Overview
- The Writers Guild of America updated its directory Thursday, November 12, 2026, listing Stephen McFeely and Michael Waldron as the film’s official 'Written by' screenwriters.
- The same entry adds several people under 'Additional Literary Material,' including Ryan Reynolds and Hugh Jackman, which outlets report as the clearest public confirmation to date that Deadpool and Wolverine are involved in the movie.
- 'Additional Literary Material' is a WGA credit for contributors whose work aided a script but did not meet the threshold for on‑screen writing credit, so the listing confirms involvement without specifying how much of their material appears on screen.
- The WGA entry also shows Waldron’s credit as 'and' rather than the ampersand form used for joint authorship, a change industry reporters interpret as indicating he worked on earlier drafts rather than co‑writing the final screenplay.
- Avengers: Doomsday remains scheduled for release on December 18, 2026, and the credits both underscore the film’s multiverse and X‑Men ties and leave open questions about the precise screen time and narrative impact of the returning characters.
