HBO's Louisiana-set drama series "Treme" has been renewed for a fourth and final season, the show's co-creator confirmed. The Hollywood Reporter said it is unclear how many episodes the fourth season of the critically acclaimed, but low-rated show will include. "We are going to be back for a Season 3.5," The Times-Picayune reported co-creator David Simon told the audience at the show's Season 3 premiere in New Orleans. "HBO, upon viewing the 10 [Season 3 episodes] that we gave them and what we've done, they want to see the end of the story. They fought very hard to give us half a loaf. We're going to take it and run." The series about Louisiana residents trying to rebuild their lives after Hurricane Katrina stars Khandi Alexander, Rob Brown, John Goodman, Melissa Leo, David Morse, Wendell Pierce and Steve Zahn.
