About Leonid Amalrik
Leonid Alekseyevich Amalrik was a Soviet animator and animation director. He was named Honoured Artist of the RSFSR in 1965. For the first few years Amalrik along with other animators focused on Disney-styled films, though he didn't tolerate them. In 1930 he returned to Mezhrabpomfilm where he co-directed his first traditionally animated short Black and White (1932) with Ivan Ivanov-Vano. During the first month of war Amalrik gathered a group of those few animators left in the city, including Olga and Nikolai Khodataev, and they produced several anti-Hitler sketches that were released under the Kino-Circus name in 1942.
