OK, New York, wipe that frown of your face. We've got tourists to soak! Our ever-resilient city, where a crisis lasts only as long as the stock market is closed, has found closure in the usual place: self-promotion. Even as our local tourist bureau, NYC & Company, was hyping the theater industry last week, the state's Empire State Development agency was crashing an unprecedented 60-second "I Love New York" commercial featuring the mayor, the governor, everyday New Yorkers, everyday celebrities and, our greatest selling point, loving portraits of city landmarks. In other words, New York needs to get back to what it does best: selling itself. True, it couldn't come at a better time. The city's economic heartbeat -- always one corned beef sandwich away from a massive coronary -- is on life-support. Some top restaurants are so quiet that they're offering three-course meals for $10. Hotels have "vacancy" signs out front. Cabbies are so desperate for business that they'll even pick up people going to Harlem. Usually, it would take a month to produce, shoot and edit a 60-second ad, but the new "I Love New York" ad is being completed in a week so it can begin airing on Oct. 8 in cities within driving distance of New York (those within FLYING distance will, understandably, not see the ad for a few more weeks). "I feel good about this job," said director Mark Claywell, whose Highway 61 production company is known for its stylish ads for the Florida Marlins, Top Flight golf balls and even Stren's fishing line (you should've seen the one that DIDN'T get away). "At least we're not selling sneakers." Kicking off a two-day shooting spree that would take him from lower Manhattan to Times Square to Central Park to Yankee Stadium and back again (you gotta have the sun setting over the Brooklyn Bridge, right?), Claywell began Friday morning at Caffe Napoli, a picture-perfect Little Italy cafe. The first shot of the day consisted of manager Giovanni Varriale joyously opening the restaurant's doors while busboy Sixto Perez smilingly carried out a podium bearing the day's menu. The postcard image was so romantic that it would've made Woody Allen blush. Although Caffe Napoli was picked because, Claywell admitted, "they were nice to us when we were location-scouting," the 62-year-old Varriale is ideal for an "I Love New York" commercial. He visited as a tourist 15 years ago, got a job in a friend's restaurant and never left. "It's a-funny," said Varriale in his thick Neapolitan accent. "I really DO a-love New York." With the shot finished, Claywell was energized. Grabbing a hand-held camera, he headed down Mulberry Street towards Canal, which is not the obvious place to film a commercial about how beautiful New York can be. Yet real life in this city IS beautiful: the sun gleaming off a tenement wall, the old guy with the smelly cigar, the Chinese guy with the hand-truck loaded eight-feet high, the Mexican man unloading vegetables, the infernal traffic, the biker with tattoos, the kid eating what appears to be chicken toenails, the Yugoslavian woman cleaning tables. "Chinatown is the most stimulating place," Claywell said, quickly exhausting his film. Next, Claywell needed a shot of the New York Stock Exchange. Even under normal circumstances, getting a 30-person crew to the corner of Wall and Broad is not easy -- but a city-provided police escort got Claywell's team through all the checkpoints. The advance unit had already filmed people going to work (the ones wearing gas masks and paper filters will, obviously, be edited out) and filmed financial reporter Maria "The Money Honey" Bartiromo reporting from the stock market floor. Unlike other celebrity footage -- Ben Stiller coming out of a cab with shopping bags? Puh-leze! -- Bartiromo, an actual New Yorker doing her actual job, helped convey the commercial's central message: Hey, we're getting back to normal. You should, too. Working like a guerilla film crew, Claywell quickly grabbed his last shot of the morning: the statue of George Washington at Federal Hall pointing to the famous sculpture on top of the stock exchange, that metaphoric representation of our indestructible national wealth. "I needed that shot," Claywell said. "It says a lot aesthetically, politically, economically." It says, more important, that we're back in business. --30--
