Question: How old was Walt Disney the year Snow White and the Seven Dwarfs was released? Passage:After the success of Walt Disney Productions' first feature-length animated film Snow White and the Seven Dwarfs (1937), filmmaker Walt Disney himself made several attempts to adapt the fairy tale "Beauty and the Beast" by Jeanne-Marie Leprince de Beaumont into one of the studio's earliest animated feature films during the 1930s and 1950s. However, the project was continuously abandoned due to the fairy tale's "static" plot and main characters. The filmmaker was also concerned about the "unnecessary intensity" required to depict Belle's imprisonment. Inspired by the unprecedented success of The Little Mermaid (1989), Walt Disney Studios chairman Jeffrey Katzenberg green-lit another attempt at adapting "Beauty and the Beast" under the direction of Richard Purdum. However, Katzenberg did not approve of Purdum's dark, somber version of the fairy tale, and ultimately ordered that it be restarted from scratch in favor of creating a Broadway-style musical film starring a strong heroine, more similar to The Little Mermaid. Opting instead for a "feminist twist" on the original story, largely in response to critics' negative reception to Ariel regarding her pursuit of Eric being her overall character, Katzenberg hired television writer Linda Woolverton, who had never written an animated film before, to write the film's screenplay.
