The Tale of Tsar Saltan
With the start of the Great Patriotic War the studio was evacuated to Samarkand along with some key animators who continued teaching students and producing films, including anti-fascist propaganda. In 1943 they returned to Moscow and released several kids movies such as "The Tale of Tsar Saltan" (1943) by the Brumberg sisters and (1945) by Ivanov-Vano — the last film to use the Soviet three-color filming process before the switch to Agfacolor. By that time Ptushko's studio at Mosfilm had been shut down and Tsekhanovsky's studio at Lenfilm — destroyed by a bomb, which basically turned Soyuzmultfilm into Russia's animation monopolist.
