Keaton, Parker, and Mulroney join cast of latest from Big Eden director Thomas Bezucha

Diane Keaton, Sarah Jessica Parker, and Dermot Mulroney have signed on to the project previously known as Hating Her for Fox 2000. Claire Danes, Rachel McAdams, and Luke Wilson are in negotiations to join the romantic comedy, which is currently untitled. Tom Bezucha writes and directs, while Michael London, whose Sideways is being toasted by many awards groups, produces. Set around Christmastime, the story revolves around a family whose favorite son (Mulroney) brings home the woman to whom he intends to propose (Parker), only to have his family turn on her. Keaton plays the matriarch and the family's emotional core. Wilson and McAdams would play Mulroney's brother and sister, while Danes would play Parker's sister. "It's an embarrassment of riches," Bezucha, who wrote and directed the 2000 gay-themed indie Big Eden, said of the cast. "You can't even dream this big." The project, which has been in development for several years, came close to being put together on several occasions, most recently a year and a half ago. "I'm humbled by the general goodwill by the town toward the script," Bezucha said. "It took the stewardship of Michael [London] to really make it jell, and Elizabeth Gabler, who really, really responded when he took it to her. It has been a long and bruising road, but you look back and think there are no regrets because you ended up where you ended up." Bezucha is a former fashion exec who worked at Polo and Coach in New York before becoming a filmmaker. He recently wrote Anyone But You, which is set up at Paramount, for producer Lynda Obst. A late February start date is planned for the untitled production, which has a budget between $10 million and $20 million.
