Larry Hagman, Patrick Duffy and Linda Gray Set for TNT's ‘Dallas’ Reboot

The new show follows J.R. Ewing's son, who clashes with his adopted cousin

J.R. Ewing is coming back to television.

Larry Hagman, who played the scheming, womanizing oil baron in "Dallas," is reprising his role, along with series originals Patrick Duffy, who plays Bobby Ewing and Linda Gray's Sue Ellen Ewing, TNT announced Tuesday.

The new show follows J.R. Ewing's son, John Ross, and Christopher, the adopted son of Bobby and Pam Ewing. The cousins clash as they try to control the family fortunes.

Josh Henderson, of "Desperate Housewives," will play John Ross, with Jordana Brewster ("Fast & Furious) cast as Elena, who is in a love triangle with Christopher (still uncast, according to a TNT rep) and John Ross (hey, it is a soap opera).

Executive producer Cynthia Cidre, who wrote "The Mambo Kings" and produced the television series "Cane," wrote the pilot based on David Jacobs's characters. Michael M. Robin is director and executive producer of the pilot.

The updated version of "Dallas" comes to TNT from Warner Horizon Television.

The original show ran from 1978-1991 and followed the Ewing family. The Ewings lived at the home of their patriarch, Jock Ewing, at Southfork Ranch.
