Jaws is a 1975 American thriller film directed by Steven Spielberg and based on Peter Benchley's 1974 novel of the same name. In the film, a giant man-eating great white shark attacks beachgoers at a New England summer resort town, prompting police chief Martin Brody (Roy Scheider) to hunt it with the help of a marine biologist (Richard Dreyfuss) and a professional shark hunter (Robert Shaw). Murray Hamilton plays the mayor, and Lorraine Gary portrays Brody's wife. The screenplay is credited to Benchley, who wrote the first drafts, and actor-writer Carl Gottlieb, who rewrote the script during principal photography.
Shot mostly on location on Martha's Vineyard in Massachusetts, Jaws had a troubled production, going over budget and past schedule. As the art department's mechanical sharks often malfunctioned, Spielberg decided to mostly suggest the shark's presence, employing an ominous and minimalistic theme created by composer John Williams to indicate its impending appearances. Spielberg and others have compared this suggestive approach to that of thriller director Alfred Hitchcock. Universal Pictures gave the film what was then an exceptionally wide release for a major studio picture, on over 450 screens, accompanied by an extensive marketing campaign with a heavy emphasis on television spots and tie-in merchandise.
Considered one of the greatest films ever made, Jaws was the prototypical summer blockbuster, regarded as a watershed moment in motion picture history, and it won several awards for its music and editing. It was the highest-grossing film until the release of Star Wars in 1977. Both films were pivotal in establishing the modern Hollywood business model, which pursues high box-office returns from action and adventure films with simple high-concept premises, released during the summer in thousands of theaters and heavily advertised. Jaws was followed by three sequels, all without Spielberg or Benchley, and many imitative thrillers. In 2001, it was selected by the Library of Congress for preservation in the United States National Film Registry as "culturally, historically, or aesthetically significant".
