Oscar-winning producer Jon Landau, who co-produced mega hits such as Titanic and Avatar, has died. He was 63. The news of his death was shared by his family in a statement to the media on Saturday. No cause of death was shared.

Director James Cameron, who had partnered with Landau for two of the biggest blockbusters of modern cinema (Titanic and Avatar), remembered his friend and close collaborator.

"(He was) a dear friend, and my closest collaborator of 31 years. A part of myself has been torn away. His zany humour, personal magnetism, great generosity of spirit and fierce will have held the centre of our Avatar universe for almost two decades. His legacy is not just the films he produced, but the personal example he set — indomitable, caring, inclusive, tireless, insightful and utterly unique,” Cameron was quoted as saying by the Associated Press.

Avatar star Zoe Saldana mourned the loss of the producer on social media and wrote, "Your wisdom and support shaped so many of us in ways we will always be grateful for. Your legacy will continue to inspire us and guide us in our journey.”

Jon Landau is survived by his wife Julie, and their sons, Jamie and Jodie.
