"Panic Room" star Kristen Stewart has signed to join Meg Ryan and Adam Brody in "In the Land of Women" for Warner Independent Pictures and Castle Rock Entertainment. Jonathan Kasdan is making his directorial debut on the film, described as a bittersweet comedy. It centers on a Los Angeles screenwriter who heads to the suburbs of Michigan to recover from a breakup. Once in the Midwest, he begins having a relationship with a mother and daughter (Ryan and Stewart) who live across the street. Anonymous Content's Steve Golin and David Kanter are producing. Shooting starts early next year on the project from a script by Kasdan. By then, Stewart will be segueing from her role opposite Tim Robbins and Dax Shepard in Columbia Pictures' "Zathura" for director Jon Favreau. She will next be seen in "Fierce People" for helmer Griffin Dunne and Lions Gate Films. Stewart recently starred in "Catch That Kid" for Fox and the indie "Speak." She's repped by the Gersh Agency and attorney Joel McKuin.
