20th Century Fox's upcoming X-Men: Dark Phoenix is not going through three months of reshoots in Montreal. The movie, written and directed by longtime X-Men producer Simon Kinberg (making his directorial debut), will instead be undergoing around two-and-a-half weeks of reshoots in the French-Canadian city later this year. Collider first broke the story that initial reports of a three-month reshoot was not true.
Originally scheduled for a Nov. 2018 release, the project was pushed back when the cast (consisting of more than a few A-list celebs) couldn't be brought back in time for reshoots after initial test screenings. As a result, reshoots needed to be postponed, causing the theatrical debut to also be bumped. It makes sense since Turner just finished filming her scenes for the final season of Game of Thrones (where she plays Sansa Stark), while James McAvoy and Jessica Chastain are working on It: Chapter Two (where they play adult versions of Bill Denbrough and Beverly Marsh respectively).
According to Collider, the reshoots include: "some additional action in the film’s third act, a couple of new scenes, and adding some shots for existing scenes," confirming reports from March on the same subject. A 2-3 week round of reshoots isn't uncommon, and most every major comic book movie goes through a similar round before release.
The film will center on a young Jean Grey (Sophie Turner), as she begins to lose control of the devastating Phoenix Force insider of her. Bringing back the old faces from First Class, Days of Future Past, and Apocalypse, Dark Phoenix will also star Jennifer Lawrence (Mystique), Michael Fassbender (Magneto), James McAvoy (Professor X), Nicholas Hoult (Beast), Tye Sheridan (Cyclops), Kodi Smit-McPhee (Nightcrawler), Evan Peters (Quicksilver), Olivia Munn (Psylocke) and Alexandra Shipp (Storm). Jessica Chastain joins the cast as a currently-unnaped mutant with the ability to shapeshift.
