Jon Landau, the Oscar-winning producer renowned for his work with director James Cameron on "Titanic" and the "Avatar" series, has died at 63. Alan Bergman, Disney Entertainment co-chairman, confirmed Landau's death on Saturday without specifying the cause.

Bergman praised Landau, saying, "Jon was a visionary whose extraordinary talent and passion brought some of the most unforgettable stories to life on the big screen. His remarkable contributions to the film industry have left an indelible mark, and he will be profoundly missed. He was an iconic and successful producer, yet an even better person—a true force of nature who inspired all around him."

Landau's career began in the 1980s as a production manager, eventually leading to his role as producer on James Cameron's "Titanic." The film became the first to surpass $1 billion in global box office earnings and won 11 Oscars, including Best Picture. "I can’t act and I can’t compose and I can’t do visual effects. I guess that’s why I’m producing," Landau joked while accepting the award with Cameron.

His collaboration with Cameron continued with "Avatar," a groundbreaking sci-fi epic that shattered box office records and remains one of the highest-grossing films ever. Landau was instrumental in the development and defense of the ambitious "Avatar" sequels.

Jon Landau is survived by his wife of nearly 40 years, Julie, and their sons, Jamie and Jodie.
