Hagman played villain J.R. Ewing throughout Dallas' original 1978 to 1991 run, as well as in two later TV movies before TNT's reboot. His character was at the center of one of television's biggest cliff-hangers after being shot by an unknown assailant, leading viewers to spend the summer of 1980 pondering, "Who shot J.R.?" The catch phrase spawned a slew of merchandise, which led to Hagman asking for a pay raise and royalties before returning the following season. The episode that revealed J.R.'s shooter is still among the highest-rated TV programs ever.

"Larry Hagman was my best friend for 35 years," she said in a statement obtained by "He was the Pied Piper of life and brought joy to everyone he knew. He was creative, generous, funny, loving and talented, and I will miss him enormously. He was an original  and lived life to the full. The world was a brighter place because of Larry Hagman."

Barbara Eden, who played the titular Jeannie, called Hagman "a key element" in her life on her Facebook page Friday. "Throughout various productions I had the pleasure of watching the Texas Tornado that was Larry Hagman," she said. Amidst a whirlwind of big laughs, big smiles and unrestrained personality Larry was always, simply Larry. You couldn't fault him for it, it was just who he was. I am so thankful that this past year I was able to spend time with him and experience yet again 'Larry' in all his Big Texas bravado... Goodbye Larry, there was no one like you before and there will never be anyone like you again."

Hagman is survived by his wife of 59 years, Maj Axelsson, who, according to reports, currently suffers from Alzheimer's. The couple had two children together.
