Game of Thrones star, Ian Gelder dead at 74.

Actor Ian Gelder, best known for his role as Kevan Lannister in Game of Thrones, has died at age 74.

Fellow actor Ben Daniels announced the news in an Instagram post confirming his death. He wrote “It is with huge huge sadness and a heavy heart broken into a million pieces that I’m leaving this post to announce the passing of my darling husband and life partner Ian Gelder,” Daniels wrote.

Gelder had been diagnosed with bile duct cancer in December and Daniels had stopped work to care for him, but “neither of us had any idea that it would all be so fast,” he added.

“He was the kindest, most generous-spirited and loving human being,” Daniels wrote in tribute to his “rock” and partner of 30 years.

Gelder was also a veteran stage actor, playing major roles including Antonio in “The Merchant of Venice” and the Duke of Clarence in “Richard III” at the Royal Shakespeare Company (RSC).
