Marti Noxon, the prolific TV writer-producer whose credits include UnReal, Glee, and Buffy the Vampire Slayer, is turning her creative eye to the silver screen.

Noxon is set to make her feature film debut with To the Bone, a dark comedy inspired by her own experience with anorexia.

Noxon will write and direct, with Bonnie Curtis and Julie Lynn of Mockingbird Pictures and Karina Miller of Sparkhouse Media producing.

“‘What doesn’t kill you makes you stronger’ not only applies to the deeply personal subject matter of To the Bone, but to simply getting a film about people with eating disorders made,” Noxon said in a statement to EW. “Without the brilliant Julie Lynn, Bonnie Curtis, and Karina Miller producing, there’s no way this project would be coming to fruition. I’m thrilled to be making my feature directing debut with this troika of fierce women in my corner.”

In a 2005 interview with The New York Times, Noxon spoke about surviving an eating disorder when she was a teenager. “I had been anorexic for about five years,” she said. “And I was really sick. I probably weighed about 70 pounds.”

Noxon, who created Girlfriends’ Guide to Divorce and co-created UnReal, also recently adapted Gillian Flynn’s bestselling novel Sharp Objects, which stars Amy Adams and is being shopped to cable and streaming networks. Noxon is also working on a TV adaptation of Sarai Walker’s subversive feminist comedy Dietland.

In addition to her TV career, Noxon’s previous feature film writing credits include screenplays for Fright Night and I Am Number Four.
