was the movie jaws based on a book
Jaws is a 1975 American thriller film directed by Steven Spielberg and based on Peter Benchley's 1974 novel of the same name. In it, a giant man-eating great white shark attacks beachgoers on Amity Island, a fictional 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.
