Lili Taylor, Alex Sharp and Brooke Smith have joined the cast of Marti Noxon’s dark comedy “To the Bone,” based on Noxon’s own experience with anorexia.

The film’s cast also includes Lily Collins, Keanu Reeves, Carrie Preston and Liana Liberato. Julie Lynn and Bonnie Curtis of Mockingbird Pictures will produce along with Karina Miller, who is also financing through her company Sparkhouse Media. Miller heads Sparkhouse with her husband and financier, Talal AlAbbar.

Additionally, Ambie Group principals Andrea Iervolino and Monika Bacardi have come on board to finance the film and are co-executive producers. The project marks the start of a broader strategic relationship between Ambi and Sparkhouse Media that will see the two companies co-finance and co-produce a slate of films together.

Ambi Distribution is handling global sales and will be introducing the project to buyers at the Cannes Film Festival.

“Nothing excites us more than seeing great material align with great talent, which is evident in ‘To the Bone,'” Iervolino said. “The Sparkhouse team has put together a tremendously commercial film, and we’re excited to not only join them on this project, but on a slate of films to follow.”

Noxon, a prolific TV writer and exec producer, is making her feature debut and has written the script. Collins will portray the lead character.

Taylor starred in the recent season on ABC’s “American Crime.” She recently appeared in “Maze Runner: The Scorch Trials” and starred in “The Conjuring,” “High Fidelity” and “Say Anything.”

Sharp won a Tony Award for playing Christopher Boone in the Broadway production of “The Curious Incident of the Dog in the Night-Time,” making him the youngest winner of the Tony Award for best actor in a play. He is also co-starring in John Cameron Mitchell’s film “How to Talk to Girls at Parties” with Nicole Kidman, Elle Fanning and Ruth Wilson.

Smith has recently appeared in a recurring role on Showtime’s “Ray Donovan.” His credits include “Interstellar” and “Silence of the Lambs.”

Sharp is repped by CAA and Elin Flack Management; Taylor is repped by APA and Circle of Confusion; and Smith is repped by Paradigm and Barking Dog Management.
