John Noble and Lyndie Greenwood have been promoted from recurring players to full-time cast members on the New York-set drama "Sleepy Hollow," Deadline said. Noble plays Jeremy, Ichabod and Katrina Crane's son, while Greenwood plays Jenny Mills, police detective Abbie's streetwise sister. Inspired by Washington Irving's classic tale, "The Legend of Sleepy Hollow," the supernatural show is about what happens when 18th century colonial soldier Ichabod Crane comes back from the dead in modern-day upstate New York and teams up with Abbie, played by Nicole Beharie, to battle the villainous Headless Horseman and save the world from impending doom. Tom Mison plays Ichabod, Orlando Jones plays Police Captain Frank Irving and Katia Winter plays Katrina.
