The death was confirmed by the agent for Hagman’s co-star Linda Gray, who said the actress was at Hagman’s bedside when he died at a Dallas hospital, according to The Sun newspaper in London.
Jeffrey Lane said another co-star, Patrick Duffy, was also present.
“They had been friends for 35 years and they had worked together for many years, so obviously it is devastating,” Lane said.
Late Friday night, Hagman’s family released a statement, saying: “Larry was back in his beloved Dallas re-enacting the iconic role he loved most. Larry’s family and close friends had joined him in Dallas for the Thanksgiving holiday. When he passed, he was surrounded by loved ones. It was a peaceful passing, just as he had wished for. The family requests privacy at this time.”
Hagman had a liver transplant in 1995 after years of alcoholism. In June 2011, Hagman revealed that he had stage 2 throat cancer.
At the time, he said: “As J.R. I could get away with anything — bribery, blackmail and adultery. But I got caught by cancer. I do want everyone to know that it is a very common and treatable form of cancer. I will be receiving treatment while working on the new Dallas series. I could not think of a better place to be than working on a show I love, with people I love.”
Despite his illnesses, Hagman returned to Dallas to film season one of TNT’s Dallas reboot and part of season two.
He married Maj Axelsson in 1954 and the couple had two children.
