I was watching the original Disney Snow White last night (on ABC Family, way too many commercials), and I noticed a similarity in the way the face was portrayed, as well as the voice, between the old apple peddler/witch, and a fairly minor character in a favorite film of mine, A Tale of Two Cities (1935 version).
Turns out they were played by the same person, Lucille La Verne. I’m willing to bet the animators studied her portrayal in that earlier film and based the mannerisms of the witch on her portrayal of The Vengeance.
How about you? What cases of unexpectedly, the same actor, have you run across lately?
