Bravo’s first scripted series, Girlfriends’ Guide To Divorce, includes a storyline about a guy separated from his wife who’s dating a CW starlet, which makes for one of the pilot episode’s funnier lines. Series creator Marti Noxon got asked about the reference and admitted she’s created a fictitious CW series which this starlet stars. It’s called Blood Sisters; it’s about twin sisters — one’s a vampire slayer and one’s a vampire.

“When are you taking Blood Sisters to the CW” a critic joked-but-not-really of Noxon, who is well known for her work on  Buffy the Vampire Slayer.

In February Bravo announced it has acquired Girlfriends’ Guide to Divorce, based on the best-selling Girlfriends’ Guide books by Vicki Iovine. The series follows Abby (Lisa Edelstein), a self-help book author who hides the fact that she’s separated from her husband, as she starts to navigate her life as a single woman in her early 40s in Los Angeles. Noxon is executive producing with Dawn Olmstead, Iovine, Meryl Poster and Adam Brooks, who directed the pilot. The series co-stars Janeane Garofalo and Beau Garrett, with Paul Adelstein and Carrie Fisher featured in the pilot.

Fisher plays Abbey’s longtime book editor/career guide.  Fisher has apparently lost a lot of weight for the new Star Wars movie. “We can say when she comes back she was in rehab,” Noxon snarked this afternoon.

Edelstein said Fisher was intimidating. “She sort of owns a room,” Edelstein said, adding, “I love her; she’s brilliant.” Panelists at the show Q&A report Fisher was quiet when she came to the set, showing up in the morning and knowing every line. She got her scenes shot quickly and, as she was leaving, said,  “You’ guys are lucky —  it’s a manic day.”

Noxon formerly worked as a consulting produer on Mad Men, after spending years working in broadcast TV where, she said, she learned “you aren’t always allowed to write what you want” — particularly at networks that love to give notes. “I’ll never forget going to Mad Men” she said, recalling her first day on the AMC drama, during which she asked what was the “theme” on which they were working.  “Screw theme — where did you learn that? Unlearn that!” Noxon says Mad Men creator Matthew Weiner responded.

“He’s a real genius. He’s a wild man,” Noxon recalled. “There was more drama in the writers’ room than on the set all the time. When I was there, it was all female [writing staff]” Hahaha, Laugh, Tears, Cry — and that was just Matt!”
