Coney Island is a 1991 documentary film that traces the history of Coney Island, the westernmost part of the barrier islands of Long Island, New York. The film covers the island's 1609 discovery by Henry Hudson, its 1870s incarnation as a respectable beach destination for city-dwellers and showcase of the new developments ushered in by the machine age, the early 20th century, when amusement parks and innovative attractions attracted hundreds of thousands of people each day, and the gradual demise of the amusements.
