A great Frank Thomas drawing of the Queen of Hearts which was recently offered at auction, and is now available on Ebay. Classic Disney villains are often portrayed in a subtle manner, like the Queen in Snow White, Cinderella's Stepmother or Maleficent.
But this bad lady is cartoony, and Frank loved working on scenes with her. He liked playing off the contrast between dainty expressions followed by over the top emotional outbursts. Actress Verna Felton gave him plenty explosive voice recordings that helped define her personality.
It's amazing to realize that she also voiced the kind Fairy Godmother in Cinderella, the movie preceding Alice. Which speaks for Verna Felton's acting range.
Below a magazine article from Silver Screen, May 1951. One of many to promote the release of Disney's Alice in Wonderland.
