Josh Henderson (“Desperate Housewives”) will play J.R’s son on TNT’s “Dallas” reboot.

According to Deadline, Larry Hagman, Linda Gray and Patrick Duffy are all (Hagman’s negotiation was understandably more fiddly, so it took a while for the ink to dry on that one) reprising their roles from the classic soap.

John Ross (Henderson) will be caught in a battle over Southfork with Bobby and Pam Ewing’s son Christopher. Previously cast Jordana Brewster will play Elena, the gorgeous daughter of the ranch’s cook who is locked into a love triangle with Christopher and John.
