OTRC: 'Dallas' renewed by TNT, 'Rizzoli & Isles' gets season 4

Larry Hagman talks to OnTheRedCarpet.com about TNT's 'Dallas' reboot in May 2012.

Cable network TNT has renewed its new "Dallas" reboot series and has also ordered a fourth season of its cop show "Rizzoli & Isles."

"Dallas" debuted on June 13 to some 6.8 million viewers. TNT announced in a statement on Friday, June 29, that it has ordered 15 new episodes, which are set to air in 2013. The latest show, which aired on Wednesday, was watched by more than 4 million people and earned a rating of 1.1 rating among viewers aged 18 to 49. It was the third most-watched cable program that night and ranked No. 1 in its time slot.

"Rizzoli & Isles" debuted in 2010 and stars Angie Harmon and Sasha Alexander as a Boston police detective who teams up with a medical examiner to solve murder cases. TNT is set to air 15 new episodes in 2013. Its latest episode, which aired on Tuesday, was watched by more than 5.4 million viewers and earned a 1.1 rating among people aged 18 to 49. It ranked fourth in its time slot.

The first installment of "Dallas" ran from 1978 to 1991. Larry Hagman, 80, reprises his iconic role of evil oil baron J.R. Ewing on "Dallas." He is one of several returning cast members, which include Linda Gray, who plays Ewing's ex-wife Sue Ellen, and Patrick Duffy, who plays his brother Bobby.

"I'm at work early," Duffy told OnTheRedCarpet.com. "My wife wonders why I'm leaving early. It's because I get to play with Larry and Linda and now a whole new group of people that are just as important to our lives as the three of us were to each other."

Hagman filmed the new "Dallas" series while battling throat cancer. He told OnTheRedCarpet.com that starring on it was like "coming home." The feeling is conveyed well via the show's sweeping theme music and intro - which shows Southfork Ranch, the lavish property that serves as the main point of conflict between the Ewing brothers.

Other recurring actors who have appeared on episodes of the new "Dallas" include Charlene Tilton, who plays relative Lucy Ewing, Steve Kanaly, who plays Southfork Ranch foreman Ray Krebbs and Ken Kercheval, who plays family nemesis Uncle Cliff.

TNT has not announced which other alums are set to appear on the show in the future. Sasha Mitchell, who played J.R.'s illegitimate son on the original "Dallas" and also starred with Duffy on the 1990s sitcom "Step By Step" as Cody "Code Man" Lambert, is not set to appear this season, OnTheRedCarpet.com has learned.

Newcomers to the "Dallas" franchise include Josh Henderson, who plays J.R.'s equally-as-evil son John Ross, Jesse Metcalfe, who plays Bobby's adopted son Christopher and actresses Jordana Brewster, Julie Gonzalo and Brenda Strong.
