Russo Brothers Say Script Stays a "Living" Document on the Set of "Avengers: Doomsday"

"Avengers: Doomsday" began filming before its screenplay was finished, according to Variety Film. Co-director Joe Russo told the Associated Press that he and his brother Anthony were not troubled by that gap, saying the pair "always view" the script as a living document. The remark points to a screenplay that keeps taking shape even after cameras start rolling.
