Born in Tiflis (now Tbilisi), he studied economics before starting his film career as an actor and later cinematographer. He directed several documentary films, including Salt for Svanetia, but was forced to withdraw from his profession after his film Nail in the boot was banned by Stalinist censors. During World War II he directed several propaganda films and worked as a cultural attaché at the Soviet embassy in the United States. During the 1950s he directed several other films, with his four final features The Cranes Are Flying, The Unsent Letter, I Am Cuba, and The Red Tent being his most famous works.
