Amazing that the first movies parents took their tots to in the ’30s and ’40s were the early Disney features. Snow White and the Seven Dwarfs, Pinocchio and Dumbo all exploited childhood traumas. Parents disappear or die, stepmothers plot the murder of their charges, a boy skips school and turns into a donkey. Kids were so frightened by these films that they wet themselves in terror. Bambi, directed by David D. Hand, has a primal shock that still haunts oldsters who saw it 40, 50, 65 years ago.
