The Russo brothers say they start production on “Avengers: Doomsday” before the script is fully finished, and they explain their approach in recent comments. Joe Russo and Anthony Russo describe making changes as actors and rehearsals shape performances, treating the script as something that develops over time.
According to the outlets, the directors connect this workflow to their experience with improvisation and rehearsal-based directing. They say they prefer to observe what actors bring to their characters and then refine the material accordingly. Deadline and Polygon both report that the Russo brothers characterize the script as “alive” or “living,” implying that it evolves during the filmmaking process rather than remaining fixed before filming begins.
While the reporting focuses on the same core justification—unfinished scripting at the start of shooting—the coverage varies slightly in phrasing and emphasis. Polygon highlights the improvisational-comedy background behind their method, while Deadline focuses more directly on how they “like to see what actors bring” and on their “living organism” description of the script.
