Celebrity John Waters Rides Again By People Staff Published on February 22, 1999 12:00 AM Share Tweet Pin Email Melanie Griffith is set to star in John Waters’s next movie, “Cecil B. Demented.” She’ll play a movie star who gets kidnapped by a gang of “cinema terrorists.” They force her to make movies with them and participate in terrorist acts against awful movies. Eventually she becomes one of them. It’s more or less a take-off on what happened to Patty Hearst (a friend of Waters) in the 1970s when she was kidnapped by the Symbionese Liberation Army and wound up robbing a bank with her captors. The new Waters film starts shooting in August in Baltimore, which is to Waters what New York is to Woody Allen.
