Grigori Alexandrov joins Eisenstein's theatrical group and becomes a close collaborator. He initially worked as an actor, writer, and assistant director. The two formed a strong creative partnership.

Alexandrov served as co-director and co-writer on some of Eisenstein's most important early films, including "Strike" and "Battleship Potemkin". He also accompanied Eisenstein on his travels to Europe and the United States. Their creative partnership flourished, and they were considered a dynamic duo of Soviet cinema.

After Eisenstein's return to the Soviet Union, Alexandrov's career path diverged. He became a successful director of musical comedies, embracing a more populist and less experimental style of filmmaking. While both remained prominent figures in Soviet cinema, their creative paths separated, potentially leading to some underlying tension.

After Eisenstein's death, Alexandrov played a role in shaping the director's legacy, sometimes emphasizing certain aspects of his work while downplaying others. He also faced criticism for his own artistic choices and for potentially benefiting from Eisenstein's misfortune during the Stalinist era. Their relationship remains a subject of scholarly debate and interpretation.
