In 1978, Hagman was offered two roles on two television series that were debuting. One was for
The Waverly Wonders and the other for
Dallas, in the role of conniving elder son and businessman J.R. Ewing. When Hagman read the
Dallas script at his wife's suggestion, they both concluded it was perfect for him. Hagman based his portrayal in part on Jess Hall Jr., the owner of Antelope Tool and Supply Company, where Hagman had worked as a young man.
Dallas became a worldwide success, airing in 90 countries, most notably the United Kingdom, where it was even enjoyed by members of that
country's royal family, and led to several successful primetime spin-offs. Hagman became one of the best-known television stars of the era. Producers were keen to capitalize on that love/hate family relationship of J.R., building anticipation to a fever pitch in "
A House Divided", the 1980 cliffhanger season finale in which J.R. is shot by an unknown assailant, leading to the world-wide "
Who shot J.R.?" phenomenon. At the beginning of the fourth season later that year, audience and actors were trying to guess "Who shot J.R.?", now one of fictional TV's most famous questions. During the media buildup, Hagman was involved in contract negotiations, delaying his return in the fourth season. Hagman held out for a higher salary. Producers were faced with a dilemma of whether to pay the greatly increased salary or to write J.R. out of the program.
Lorimar Productions, the makers of the series, began shooting different scenes of
Dallas that did not include Hagman. In the midst of negotiations, Hagman took his family to London for their July vacation. He continued to fight for his demands and network executives conceded that they wanted J.R. to remain on
Dallas. Hagman did not appear in the first episode of the new season until the final few minutes. From then on, Hagman became one of the highest-paid stars in television. At the beginning of the 1980–81 season, writers were told to keep the storylines away from the actors until they really found out who actually shot J.R. and three weeks passed until the culprit was revealed on November 21, 1980, in a ratings record-breaking episode. For his performance as J.R. Ewing, Hagman was nominated for two
Emmy Awards for Outstanding Lead Actor in a Drama Series in 1980 and 1981, but did not win. He was also nominated for four
Golden Globe Awards, between 1981 and 1985. He was nominated for a
Soap Opera Digest award seven times for Outstanding Villain on a Prime Time Serial, Outstanding Actor in a Leading Role on a Prime Time Serial, Favorite Super Couple: Prime Time and Outstanding Actor in a Comic Relief Role on a Prime Time Serial and won five times. Hagman received the Golden Plate Award of the
American Academy of Achievement from Academy member
Ray Lee Hunt at the 1981 Achievement Summit in Dallas. In 1984, co-star
Barbara Bel Geddes left
Dallas, following a contract dispute that had resulted from her March 1983
quadruple heart bypass surgery. At one point, Hagman suggested to his real-life mother Mary Martin that she play Miss Ellie, but she rejected the suggestion and Bel Geddes was briefly replaced by
Donna Reed for the 1984–1985 season, before Bel Geddes returned in better health for the 1985–1986 season. By the end of its 14th season in 1991, ratings had slipped to the extent that CBS decided to end
Dallas. Hagman was the only actor to appear in all 357 episodes. He had also made five guest appearances on the
Dallas spin-off series
Knots Landing in the early 1980s. Some years after
Dallas ended, Hagman appeared in two subsequent
Dallas television movies:
J.R. Returns in 1996 and
War of the Ewings in 1998. Hagman reprised his role as J.R. Ewing in
TNT's continuation of Dallas, which began in 2012. In 2011, while filming the new series, Hagman said, "Of course it's fun to play the villain." As a result of Hagman's death in 2012, his character J.R. was killed off in season two of
Dallas. Unused footage of Hagman was used in season three as part of that season's story arc, which aired in 2014. ==Other work==
