The last time a John Waters movie was made into a musical, it made a tremendous splash on Broadway and went on to spawn a successful movie that is still raking in the bucks. So no doubt that the producers of Cry-Baby, the new musical based on Waters' 1990 movie of the same name, are hoping to meet with similar success. A send-up of old Elvis films and other "bad boy" flicks of the '50s, Cry-Baby starred Johnny Depp as a juvenile delinquent who falls for the classic good girl. The musical version, which has a book by Hairspray scribes Thomas Meehan and Mark O'Donnell, is expected to start previews on Broadway in March 2008, with an April opening.
