Rebecca Romijn told a Hall H interviewer at San Diego Comic‑Con that she is “not quite sure” her Mystique work on Avengers: Doomsday is finished because “the script hasn’t… they haven’t finished writing it,” confirming weeks of online speculation about on‑set rewrites. The admission lands three months after cameras began rolling under the working title Apple Pie 1 at Pinewood Studios in Buckinghamshire.
Marvel Studios president Kevin Feige, questioned at a separate press event, said every film starts with a complete screenplay yet undergoes “plus‑ing” daily and praised cast input as production continues. Writing duties sit with Stephen McFeely and, as confirmed last week, Loki creator Michael Waldron, who was asked to polish pages while shooting progresses.
The Russo brothers are directing the ensemble feature, now aiming for 18 December 2026 after Disney moved it from its May slot during the spring schedule shuffle. Re‑branded last July to replace an abandoned Kang storyline, the film brings Robert Downey Jr. back to the Marvel fold, this time as an alternate‑universe Doctor Doom.
Cast lists released since Comic‑Con place Pedro Pascal’s Fantastic Four, Thunderbolts regulars led by Florence Pugh, and original X‑Men actors Patrick Stewart and Ian McKellen alongside returning Avengers such as Chris Hemsworth and Tom Hiddleston.
Industry voices point to a wider debate about blockbuster planning; director James Gunn recently argued that mounting productions without locked scripts signals “a dying movie industry,” remarks many observers linked to Marvel’s evolving approach. For now, Romijn says the secrecy is part of the job, while Feige maintains that page‑by‑page refinement is the studio’s hallmark, setting up a race to freeze the story before reshoots and heavy visual‑effects work begin in early 2026.
