The hit show is set to return to the small screen in 2012, with most of its original cast - including Larry Hagman, Patrick Duffy, and Linda Gray - lining up alongside newcomers Jesse Metcalfe, Brenda Strong and Jordana Brewster.
Plotlines for the show's comeback have been kept under wraps by producers but now Metcalfe has let slip one surprising development for the Texan dynasty - they're moving into trading more environmentally-friendly fuel.
Metcalfe tells British magazine You, "I play Christopher Ewing, Bobby Ewing's adopted son. He's trying to move Ewing Enterprises into the next generation - alternative energy and all that. There's a bit of social commentary, too, about what's going on with our own energy crisis."
