paragraph_text: Decades later, during the production of Who Framed Roger Rabbit in 1987, the Disney studio resurrected Beauty and the Beast as a project for the satellite animation studio it had set up in London, England to work on Roger Rabbit. Richard Williams, who had directed the animated portions of Roger Rabbit, was approached to direct but declined in favor of continuing work on his long - gestating project The Thief and the Cobbler. In his place, Williams recommended his colleague, English animation director Richard Purdum, and work began under producer Don Hahn on a non-musical version of Beauty and the Beast set in 19th - century France. At the behest of Disney CEO Michael Eisner, Beauty and the Beast became the first Disney animated film to use a screenwriter. This was an unusual production move for an animated film, which is traditionally developed on storyboards rather than in scripted form. Linda Woolverton wrote the original draft of the story before storyboarding began, and worked with the story team to retool and develop the film.
