The island where “Jaws” was filmed had a real-life shark scare Thursday, when an unconfirmed sighting of a great white forced the closure of two beaches. South Beach on Martha's Vineyard was closed for a short time, and swimmers were kept out of the water at State Beach in Edgartown, the Massachusetts Department of Conservation and Recreation said. A plane was dispatched to try to confirm the sighting, but no shark was spotted, said Lisa Capone, a spokeswoman for the state Executive Office of Energy and Environmental Affairs. In 1974, Steven Spielberg chose Martha's Vineyard for filming the movie version of “Jaws,” depicting a series of deadly great white attacks in the fictional community of Amity.
