‘Avengers: Doomsday’ Shot Without a Finished Script, but Co-Director Joe Russo Says ‘We Always View’ the Screenplay as a ‘Living Organism’

Avengers: Doomsday began filming without a finished script, a move the Russo brothers describe as intentional improvisation. Club reports the directors started production because they “just love improv,” while Deadline quotes them saying they “like to see what actors bring to the characters.” Variety adds that co‑director Joe Russo treats the screenplay as a “living organism,” suggesting the narrative will evolve on set.

Yahoo notes the directors do not see themselves as responsible for correcting recent MCU missteps, framing the improvisational approach as a creative choice rather than a fix. Future coverage will likely track any studio statements or actor feedback as the film progresses toward post‑production.

The approach may influence audience expectations for the franchise's next chapter.
