LOS ANGELES (AP) — Jon Landau, an Oscar-winning producer who worked closely with director James Cameron on “Titanic” and the “Avatar” series, has died. He was 63. Landau’s family announced his death Saturday. No cause of death was given. Landau’s partnership with Cameron led to three Oscar nominations and a best picture win for 1997’s “Titanic.” Together the pair account for some of the biggest blockbusters in movie history, including “Avatar” and its sequel, “Avatar: The Way of Water.” The trio of films are among the highest grossing movies of all time. In a statement, Cameron says Landau “will be remembered as much for his vast generosity of spirit as for the movies themselves.” (Photo: AP)
