Remaining intact through totalitarian times and productive in periods of censorship regulations, Mosfilm continues to be Russia’s largest and most prolific film studio. Opening its doors in the years following the October Revolution, the studio has released films by such auteurs as Sergei Eisenstein and Andrei Tarkovsky, whose works hold prominent places in the worldwide film canon. The National Gallery of Art’s “­Envisioning Russia: Mosfilm Studio” celebrates the last nine decades of Russian cinema with a range of well- and lesser-known works. Eisenstein’s Battleship Potemkin, simultaneously a classic, emotionally wrenching work of montage and an affecting slice of Soviet agitprop, is the most renowned of the films in the series. It is, however, only one of the many Mosfilm releases offering insight into the strange relationship between creativity and state ideology in a country characterized by its idiosyncratic intensity in art, politics, and philosophy. The series runs to Sunday, June 29, at the National Gallery of Art’s East Building Auditorium, 4th St. & Constitution Ave. NW. Free. (202) 737-4215.
