FX has scheduled its shortened second season of “Dirt,” while Showtime has firmed up plans to bring back another edition of “Big Brother: After Dark.”

“Dirt” had been given a full 13-episode order by FX, but just seven segs had been written before the writers strike. Cabler has decided to go ahead and run season two, launching Sunday, March 2 at 10 p.m.

Show stars Courteney Cox as the editor of a celeb tabloid. Cox, David Arquette and Joel Fields exec produce; show comes from ABC Studios and FX.

“Big Brother: After Dark” move was expected (Daily Variety, Jan. 8); show launches Tuesday, Feb. 12 at midnight on SHO2, Showtime’s sister channel. The “After Dark” edition airs three hours nightly, seven days a week, and features a live video feed from the “Big Brother” house.

“Big Brother” launches its first edition outside of summer on Feb. 12 at 9 p.m. on CBS. Showtime first launched “Big Brother: After Dark” during last summer’s edition of the reality hit; cabler was pleased with the numbers in what’s otherwise a little-watched time period.

“I’m amazed at how much curiosity there is about what goes on in the Big Brother house after the lights are out, but what better place to present that than on Showtime, where we have a lot of on-air real estate in the wee hours of the morning,” Showtime Entertainment prexy Bob Greenblatt said.

Endemol produces “Big Brother,” which comes from exec producers Allison Grodner and Rich Meehan.
