Patrick Duffy and Linda Gray will also appear in the pilot that’s based on characters created by David Jacobs and executive produced by Cynthia Cidre (Cane).

The original Dallas aired from 1978 to 1991 and followed the Ewing family of Southfork. (Hagman played J.R. Ewing, Gray played his wife, and Duffy portrayed J.R.’s younger brother Bobby). The modern story will focus on the Ewing offspring – J.R. Ewing’s son, John Ross, and the adopted son of Bobby and Pam Ewing, Christopher – as they clash over the future of the family dynasty.

Josh Henderson (Desperate Housewives) will play John Ross while Jordana Brewster (Fast & Furious) will play Elena, who is involved in a love triangle with Christopher and John.

Hagman told EW in September that he continues to make appearances on behalf of Dallas, which syndicates in 60 countries today. ”It’s like an annuity, really,” Hagman said. ”I go out, they adore me, and then they pay you. What better job can you have?”

This isn’t the first time that someone’s tried to revive the Texas oil family drama that aired from 1978 to 1991. In 2006, Twentieth Century Fox decided to adapt the soap for the big screen, closing deals with John Travolta, Jennifer Lopez, and Luke Wilson. But then research indicated that the Dallas brand didn’t mean much to younger moviegoers, says a source close to the project. Travolta and Lopez soon dropped out.
