The project is based on the Broadway musical written by Stephen Sondheim and James Lapine, which incorporates several fairy tale characters such as Cinderella, Rapunzel, and Little Red Riding Hood with the story of a baker who attempts to start a family with his wife. James Lapine is currently writing the screenplay adaptation, which will feature new songs by Stephen Sondheim.
It isn't clear yet if Into the Woods will be Rob Marshall's next project. He also has The Thin Man in development, also with Disney, which has Johnny Depp attached to star. There is also the possibility he will return to direct Pirates of the Caribbean 5, although Terry Rossio is still working on the screenplay.
