Dallas, one of the pioneers of the longstanding primetime soap, is getting a second shot at the small screen, and TV legend Larry Hagman, 79, who played iconic oil baron J.R. Ewing in the '70s and '80s, will be front-and-center in the show's reprisal, which will follow the next generation of Ewings — cousins John Ross and Christopher — in their fight over the family dynasty.

Hagman won't be the only familiar face gracing the new TNT show next year. Linda Gray and Patrick Duffy have also agreed to sign on to the new enterprise, in their roles as J.R's wife, Sue Ellen, and his younger brother, Bobby. New arrivals will include Desperate Housewives' Jesse Metcalfe as Christopher and 90210's Josh Henderson as John Ross. Jordana Brewster, from the Fast & Furious franchise, will play the role of Elena Ramos, who is caught in a love triangle between the two cousins.

Helmed by The Closer and L.A. Law director Michael M. Robin, the new Dallas promises just as much disfunction and scandal as ever. The show is mostly remembered for its famous "Who Shot J.R.?" cliffhanger in 1980, which remains one of the most watched television episodes in history. The old Dallas had a 13 season run from 1978 to 1991. The new version will premiere in the summer of 2012.
