Robert Redford’s son, James, an activist and filmmaker, has died at the age of 58.

James Redford died on October 16 after being diagnosed with liver cancer, his wife Kyle confirmed via Twitter.

Robert Redford’s publicist, Cindi Berger, said: “The grief is immeasurable with the loss of a child.”

“Jamie [James] was a loving son, husband and father,” added Berger, who asked for privacy for the Redford family “during this difficult time”.

“His legacy lives on through his children, art, filmmaking and devoted passion to conservation and the environment.”

James Redford made documentary films, including The Big Picture: Rethinking Dyslexia.

His latest film Playing Keeps, which explored the importance of play and downtime in our lives, was given a virtual premiere online at this month’s Mill Valley Film Festival in California.

His wife of 32 years, Kyle, shared the news of his death online, alongside pictures of the couple and their two children.

Kyle Redford tweeted: “Jamie died today. We’re heartbroken. He lived a beautiful, impactful life & was loved by many. He will be deeply missed. As his wife of 32 yrs, I’m most grateful for the two spectacular children we raised together. I don’t know what we would’ve done w/o them over the past 2yrs.”

James Redford’s wife told the Salt Lake Tribune that he had discovered the cancer diagnosis late last year while awaiting a liver transplant.

His liver disease had returned two years ago, she added.

Robert Redford, 84, has three other children, including the actress Amy Redford.
