Filming began on September 23, 2006. The Marcy Avenue Armory in Williamsburg was used for the interior of Neville's home, while Greenwich Village was used for the exterior. Other locations include the Tribeca section of lower Manhattan, the aircraft carrier "Intrepid", the Kingsbridge Armory in the Bronx, and St. Patrick's Cathedral.
