Richard D Zanuck, the producer of Jaws and Driving Miss Daisy, died on Friday in LA, a spokeswoman for his production company told TheWrap. He was 77. The cause of death was a heart attack.The son of famed 20th Century Fox head Darryl F Zanuck, he would make his own indelible mark on the movie business by championing a then-unknown director named Steven Spielberg. Their 1975 adaptation of Peter Benchley’s pulpy novel would usher in a new era of summer blockbusters and fundamentally alter the type of movies that the industry made. The DNA of Jaws, which at the time was the highest grossing movie in history, can still be detected in such recent hits like The Avengers and Avatar, cinematic spectacles that entice audiences through a combination of special effects and easily digestible plots.
