The film, which as of now is to be called, simply, "World Trade Center," tells the story of two Port Authority police officers, John McLoughlin and Will Jimeno, who were the last two rescue workers pulled from ground zero alive. It is billed as an uplifting story about everyday New Yorkers helping one another amid a cataclysmic tragedy. So for 20 days in October and November, the cast and crew were in the New York metropolitan area, filming at the police desk in the Port Authority bus terminal and along the route the officers took downtown on the morning of Sept. 11, 2001. They filmed scenes on the Staten Island ferry, the Long Island Rail Road and a subway train in Brooklyn. They shot in Clifton, N.J., near Mr. Jimeno's house, and in other suburbs.
