Sleeping Beauty is a unique production in the Disney canon. The first time a single artist was given total control over the look and feel of the entire production, the angular lines, static backgrounds and minimalist dialogue are inspirations from medieval art, and would never be repeated again by the studio, despite their success.
Briar Rose, or Princess Aurora, is barely present through most of the film. Her first line in the film is spoken at the 19 minute mark, and 20 minutes later she speaks her last line. In fact, she’s second only to Dumbo for fewest lines spoken by a title character. Instead, despite the film’s title, the vast majority of the story centres around the three fairies trying to protect the young woman and in so doing undo the curse of a vicious sorceress.
