Russian and later Soviet cinema was a hotbed of invention, resulting in world-renowned films such as The Battleship Potemkin.[2] Soviet-era filmmakers, most notably Sergei Eisenstein and Andrei Tarkovsky, would go on to become among of the world's most innovative and influential directors.[3][4] Eisenstein was a student of Lev Kuleshov, who developed the groundbreaking Soviet montage theory of film editing at the world's first film school, the All-Union Institute of Cinematography.[5] Dziga Vertov's "Kino-Eye" theory had a huge impact on the development of documentary filmmaking and cinema realism.[6] Many Soviet socialist realism films were artistically successful, including Chapaev, The Cranes Are Flying, and Ballad of a Soldier.[citation needed]
