had become known. The film took four years to complete, and was released in 1972. Aleksander Ptushko died a few months after its release, aged 72. He spent his last months writing a script for The Tale of Igor's Campaign adaptation which he was going to direct despite already been seriously ill. He was survived by his daughter from the first marriage Natalia Ptushko who worked as an assistant director at Mosfilm. American Re-Edits of Ptushko Films When Ptushko's films were released in the United States, they were dubbed and re-edited, and the names of most of the cast and crew members were replaced with pseudonyms. While these practices were common at the time for releases of foreign films in the United States that were aimed at a mainstream audience, these modifications also served to obscure the Russian origin of these films to improve their commercial prospects during the Cold War.
