Jon Landau, a producer who won an Academy Award and collaborated closely with director James Cameron on three of the most successful blockbusters of all time, including Titanic and two films based on the Avatar franchise, has passed away.  The film Titanic is the first movie in history to ever earn more than one billion dollars worldwide.

The passing of Jon was announced by his family on Saturday. He was 63 years old.  The cause of death was not confirmed.

Titanic which was released in 1997 received three nominations for the Academy Award for Best Picture, because of Jon's collaboration with James. Together, they hold the credit for some of the most successful blockbusters in the history of film, such as the original film Avatar and its sequel, Avatar: The Way of Water.

James was enthusiastic about the project; however, he was unable to direct it because of his commitments to "Avatar." In its place, Jon collaborated with director Robert Rodriguez to bring the film to a successful conclusion.

The manga adaptation of "Alita: Battle Angel" was brought to the big screen in 2019, and he was also a significant contributor to its production.

He was survived by his wife Julie Landau

Julie Landau, 61, is Jon Landau's wife for close to forty years during their marriage. Jamie and Jodie are two adorbale sons of the couple and both are now grew up.

 Among his siblings, Landau is the brother of Broadway director Tina Landau, Kathy Landau, who is the executive director of Symphony Space, and Les Landau, who is the director of Star Trek.
