Question: What is the date of death of the director of film The Stone Flower (1946 Film)?
Sentence (from "Aleksandr Ptushko"): Ptushko is frequently (and somewhat misleadingly) referred to as "the Soviet Walt Disney," due to his prominent early role in animation in the Soviet Union, though a more accurate comparison would be to Willis O'Brien or Ray Harryhausen.
Relevant evidence: No
