EXCLUSIVE: Lily Collins has been set to star in To the Bone, the feature directorial debut of TV writer Marti Noxon. Noxon also wrote the dark comedy, which is inspired by her own experiences with anorexia. Principal photography kicks off at month’s end in Los Angeles.

Julie Lynn and Bonnie Curtis of Mockingbird Pictures (Rodrigo Garcia’s Last Days in the Desert and Albert Nobbs) are producing with Karina Miller, who also is financing through Sparkhouse Media, the newly launched production and finance company she heads with husband Talal AlAbbar. To the Bone is that outfit’s first project on a slate aiming to produce three to five films a year with budgets up to $30M.

Collins, whose credits include the Snow White tale Mirror Mirror and The Mortal Instruments: City of Bones, is next up on the big screen in the untitled Warren Beatty movie. She also recently landed the young female lead opposite Matt Bomer in The Last Tycoon, Amazon’s drama pilot based on F. Scott Fitzgerald’s final unfinished novel.

“Lily is a rare bird. She’s got a depth of feeling and heart that immediately won me over,” said Noxon, who co-created Lifetime’s UnReal and created Girlfriends’ Guide to Divorce at Bravo. “I feel blessed to be working with a young woman with such talent, beauty and brains.”

Said Collins: “I’m incredibly honored to be part of such a powerful story of love, self-doubt, and the courage it takes to fight for survival. I believe this film has the potential to shine a light on something that’s becoming more prevalent within our society every day and let those suffering know they’re not alone.”

Noxon, whose TV credits also include Buffy the Vampire Slayer and Mad Men, on the film side wrote I Am Number Four and Fright Night and recently adapted the Gillian Flynn bestseller Sharp Objects with Amy Adams attached.

Collins is repped by CAA, LBI Entertainment and Sloane Offer. Noxon is repped by WME and Hansen Jacobson.
