At a recording session, Lucille La Verne, the voice of the Wicked Queen, was told by Walt Disney's animators that they needed an older, raspier version of the Queen's voice for the Old Witch. La Verne stepped out of the recording booth, returned a few minutes later, and gave a perfect "Old Hag's voice" that stunned the animators. When asked how she did it, she replied, "Oh, I just took my teeth out."
Walt Disney wanted to keep Snow White's voice as a special one-time sound, and held Adriana Caselotti to a very strict contract. Except for a tiny bit part in Il mago di Oz (1939), she never had a real singing part in a movie again, though she was a classically trained singer.
Some animators were opposed to the name Dopey, claiming that it was too modern a word to use in a timeless fairy tale. Walt Disney made the argument that William Shakespeare used the word in one of his plays. This managed to convince everyone, although any reference to the term "dopey" is yet to be found in any of Shakespeare's work. Although Shakespeare does use the term "foolish" in Twelfth Night, as well as "zed"; (for z, meaning dumbest of the dumb); these could have all been alternative names for Dopey since they were found in Shakespeare. "Half-wit", "Dunce" and "Jester" were all similar terms that were commonly used at the time, they could have been Dopey's name also. The original names of the Dwarfs, before Disney renamed them, were Snick, Glick, Blick, Flick, Plick, Whick and Quee.
Walt Disney Studios in Burbank California was built with the profits from Biancaneve e i sette nani (1937).
