Before the animation process began, a live-action reference version was filmed with live actors in costume serving as models for the animators in which Walt Disney insisted on because he wanted the characters to appear "as real as possible, near flesh-and-blood." However, Milt Kahl objected to this method, calling it "a crutch, a stifling of the creative effort. Anyone worth his salt in this business ought to "know" how people move." Helene Stanley was the live action reference for Princess Aurora. The only known surviving footage of Stanley as Aurora's live-action reference is a clip from the television program "Disneyland", which consists of the artists sketching her dancing with the woodland animals. Stanley previously provided live-action references for "Cinderella" and later for Anita from "101 Dalmatians", and portrayed Polly Crockett for the TV series "Davy Crockett, King of the Wild Frontier".
