Star Wars creator George Lucas is producing a CGI musical about fairies. Work on the project is currently under way at Lucas’s Skywalker Ranch in Marin County, California. Plot details are being kept under wraps, but the story is said to center around tiny mythological creatures.

Lucas hatched the idea for the untitled animation and enlisted the writer of the Spiderwick Chronicles, David Berenbaum to pen the script. TMNT director Kevin Munroe has signed up to helm the project, which will pull in music from a variety of different sources.
