As the art department's mechanical sharks often malfunctioned, Spielberg decided mostly to suggest the shark's presence, employing an ominous and minimalist theme created by composer John Williams to indicate its impending appearances. Shot mostly on location at Martha's Vineyard in Massachusetts, Jaws was the first major motion picture to be shot on the ocean and consequently had a troubled production, going over budget and schedule.
The screenplay is credited to Benchley, who wrote the first drafts, and actor-writer Carl Gottlieb, who rewrote the script during principal photography. Murray Hamilton plays the mayor, and Lorraine Gary portrays Brody's wife. It stars Roy Scheider as police chief Martin Brody, who, with the help of a marine biologist ( Richard Dreyfuss) and a professional shark hunter ( Robert Shaw), hunts a man-eating great white shark that attacks beachgoers at a summer resort town.
Jaws is a 1975 American thriller film directed by Steven Spielberg, based on the 1974 novel by Peter Benchley.
