Jon Landau, who produced several of Hollywood’s biggest films including Titanic and Avatar, has died at the age of 63.

Landau passed away on Saturday, July 6th, following a battle with cancer, according to TheWrap.

A former executive vice president of feature film production at Twentieth Century Fox, Landau later made producing his primary focus through high-profile collaborations with director James Cameron. As a producer on Titanic, Landau helped shepherd the first film to gross $1 billion at the box office and later won an Academy Award for Best Picture.

Landau also worked closely with Cameron on 2009’s Avatar and its 2022 sequel, Avatar: The Way of the Water. As of present day, Avatar, The Way of the Water, and Titanic rank as three of the four highest-grossing films of all time.

Landau’s other producing credits included Honey, I Shrunk the Kids, Dick Tracy, Solaris, and Alita: Battle Angel.
