Joe Russo Says Avengers: Doomsday Script Continued to Evolve During Production
Avengers: Doomsday was filmed without a fully locked screenplay, according to comments from co-director Joe Russo reported by Variety. Russo explained that he and his collaborators treat a screenplay as something that continues to develop rather than as a document fixed before cameras roll.
Russo characterized that approach as a normal part of their process, describing the script as a living, changing piece of work. In practice, that kind of method allows a production to adjust writing as filming progresses, responding to what is working on set while the movie is still taking shape.
Large-scale productions often continue refining material during photography, and Russo's remarks offer a brief look at how the directing team views that flexibility — not as a departure from their plan, but as part of how they have chosen to make the film.
The comments concern the filmmaking process only. No story details from Avengers: Doomsday were disclosed in the report.
