Larry Hagman who played the conniving villainous J.R. — head of the oil-rich and powerful Ewing clan on both the original an recent sequel of the world popular TV series Dallas - died this afternoon at Medical City in Dallas. The cause was cited as recent complications from a year-long bout with cancer. He was 81. “Larry was back in his beloved Dallas re-enacting the iconic role he loved most,” his family said in a written statement. “Larry’s family and close friends had joined him in Dallas for the Thanksgiving holiday. When he passed, he was surrounded by loved ones.” Deadline has learned that among those at his bedside were his longtime Dallas co-stars Linda Gray and Patrick Duffy.
