A young woman battles her body and her nihilism in the first trailer for Marti Noxon’s “To the Bone.” “I just don’t see the point,” Ellen (Lily Collins, “Rules Don’t Apply”) tells her doctor (Keanu Reeves) in the spot. She’s struggling to find meaning in life and dealing with the consequences of a debilitating eating disorder. “I’m not going to treat you if you’re not interested in living,” he says.

Ellen is anorexic, and as much as she tells herself that she has things “under control,” she doesn’t. She faints as a result of starving herself. “The way that you’re going, one day you won’t wake up,” her doctor warns. The incident seems to be what lands Ellen in an unconventional treatment program where she bonds with other residents. “Some of them actually seem like they’re doing OK — like they might get lives and be semi-interesting people,” an uncharacteristically optimistic Ellen says.

The semi-autobiographical film marks Noxon’s feature directorial debut. “I was anorexic and bulimic from the time I was about 13 until I was almost 25,” the “UnREAL” co-creator told us. When we asked her what she’d like audiences to think about after watching the movie, she said, “I hope they will have a better understanding that women and men who have eating disorders have a disease that is real — that it’s not an issue of vanity. And I hope they will look more closely at their own self-critical voices and think about being kinder to themselves,” she added.

Noxon has penned episodes of “Glee,” “Mad Men,” and “Grey’s Anatomy.” She is serving as showrunner on HBO’s upcoming adaptation of “Gone Girl” author Gillian Flynn’s “Sharp Objects.” Amy Adams plays a reporter investigating the murder of two pre-teen girls in the series.

“To the Bone” will be available to stream on Netflix July 14. The film made its world premiere at Sundance this January.
