When we heard that TNT was resuscitating “Dallas” – yes, the drama that ran on CBS from 1978 to 1991 — we were skeptical. And we still are. But two of the stars of the show, actresses Jordana Brewster and Julie Gonzalo, were in Boston to promote the show Wednesday, and they swear it’s Southfork just like we remember. (In case you’ve forgotten the fictional ranch that was home to the Ewing clan, TNT’s brought back Larry Hagman, who played J.R. Ewing, Patrick Duffy, who played Bobby Ewing, and Linda Gray, who played Sue Ellen, to help you remember.) “Yeah, there are a lot of expectations, and that’s a double-edged sword,” admitted Gonzalo, who was barely born when the show was popular. “Because there was no DVR or TiVo, you had to be in front of the TV on Friday night to watch it, and people were.” The show, which premieres June 13, is about the next generation of scoundrels and backstabbers. Brewster plays an ambitious geologist looking for oil, and Gonzalo is a lawyer engaged to one of Bobby Ewing’s boys. “We’re dealing with the repercussions of Sue Ellen not holding her baby,” said Brewster. “He turns into a little monster and now the whole world has to contend with him.” Before leaving Boston, the actresses made a pit stop at Tiffani Faison’s barbecue joint Sweet Cheeks. They are from “Dallas,” after all.
