Larry Hagman, who created one of American television's most amoral villains as oilman J.R. Ewing in Dallas has died, according to reports in Dallas Morning News.
Mr Hagman, 81 died at a Dallas hospital of complications from his battle with cancer, the newspaper said, quoting a family statement.
He had suffered from cancer and cirrhosis of the liver in the 1990s after decades of drinking.
Hagman's mother was stage and movie star Mary Martin and he became a star himself in 1965 on "I Dream of Jeannie," a popular television sitcom in which he played Major Anthony Nelson, an astronaut who discovers a beautiful genie in a bottle.
Dallas, which made its premiere on the CBS network in 1978, made Hagman a superstar. The show quickly became one of the network's top-rated programs, built an international following and inspired a spin-off, imitators and a revival in 2012.
