"Shrek: The Musical" director Jason Moore has signed to helm MGM's re-imagining of "Valley Girl" as a musical feature. Amy Talkington's updated screenplay spurred studio head Mary Parent and the first-time filmmaker to move on it quickly. Idealogy's Sean Bailey and Matt Smith, who are producing, pitched MGM last summer on their fresh approach to revamping the 1983 cult comedy, which starred Nicolas Cage and Deborah Foreman in a romance that bridged the '80s punk scene and suburban San Fernando Valley culture.
