Cityfile: New York's Most Notable and Influential

• Stephen Daldry, the director of The Hours, The Reader, and the Broadway production of Billy Elliot, The Musical, has picked up a new home: He paid $3.8 million for a five-floor townhouse in Chelsea. Daldry clearly has some work ahead of him. The 4,600-square-foot property located at 347 West 21st Street is currently configured as a three-unit house, according to the listing, and is in need of renovation. But he scored a pretty decent discount in the process. The home had been on the market for $4.775 million. [Cityfile, Corcoran]
