The Tale of Despereaux (opening December 19 throughout San Diego) looked promising. The trailer was amusing and took a laid back approach to selling its story rather than the usual hysterical, frantic, in your face pitch that American animation feels compelled to use. It was based on a popular and well-written children's book by Kate DiCamillo that bore the subtitle: "Being the story of a mouse, a princess, some soup, and a spool of thread." The animation looked state of the art with an appealing big-eared mouse hero. The film also boasted some talented voice actors in Kevin Kline, Matthew Broderick, Tracey Ullmann, Robbie Coltrane, Frank Langella and Dustin Hoffman. So what went wrong?
