Jaws movie legend dies at age of 77.
He became the youngest ever studio head at 27 when his father, Darryl F Zanuck, appointed him head of 20th Century Fox in 1962.
Other studio hits included Oscar-winning The Sound of Music, Patton and The French Connection.
He was fired in 1970 and teamed up an old colleague to form an independent company, working with then relatively unknown director Steven Spielberg, who said: "He taught me everything I know about producing."
Planet of the Apes and Sweeney Todd director Tim Burton added: "He was like family to me. A mentor, friend and father figure."
