Screenwriter Tom Mankiewicz, who penned several James Bond films and was an uncredited writer on the first two Superman movies, died Saturday in Los Angeles after a battle with cancer, the AP reports. He was 68. After being hired to rewrite 1971’s Diamonds Are Forever, Mankiewicz went on to pen Live and Let Die and The Man With the Golden Gun; he also worked on The Spy Who Loved Me and Moonraker. A respected script doctor, he received credit as a creative consultant on Superman and Superman II after director Richard Donner brought him in to rewrite those movies. Mankiewicz directed the 1987 movie Dragnet, and served as a creative consultant on Hart to Hart, directing and penning several episodes. Mankiewicz came from a well-known Hollywood family: His father, Joseph L. Mankiewicz, wrote and directed  All About Eve, while his uncle, Herman J. Mankiewicz, co-wrote Citizen Kane. His cousin is Turner Classic Movies host Ben Mankiewicz. According to Ben, Mankiewicz was planning to return this fall to teach graduate film classes at Chapman University in Orange, Calif.
