Larry Hagman, Patrick Duffy and Linda Gray say it was emotional being back on set in the Dallas reboot.

The trio – known by cast and crew as ‘The Big Three’ – are reprising their iconic roles from the original series in the new TV show, with the actors back as warring brothers JR and Bobby Ewing and Linda stepping into Sue Ellen’s shoes again.

Larry, 80, said: “I was very happy to be back on set with the beautiful Linda.”

“I’ve been married twice to her and divorced twice,” he joked.

Patrick, 63, added: “I have this emotional, heartfelt scene with Larry. It was the first time we’d worked together in 20 years, and it just killed me, in a good way.”

Since we last saw them in the show, which ran from 1978 to 1991, the pair have lost their parents. Bobby has married Sue Ellen’s friend Ann (Brenda Strong) and become head of Southfork, and JR has spent time in a nursing home following his breakdown.

Sue Ellen is pursuing a career in politics and, although she’s not JR’s put-upon wife any more, she’s still as ruthless as ever.

Linda, 71, said: “We haven’t mellowed at all – and you wouldn’t want us to!”

The original Dallas stars will be joined by a new generation in the revamped show, including Jordana Brewster, Josh Henderson and Desperate Housewives hunk Jesse Metcalfe.

Dallas starts on Five on Wednesday, September 5.
