VIDEO: Chloë Grace Moretz Battles a Mysterious Illness in Trailer for Charlize Theron-Produced 'Brain on Fire'

“Suspiria” starlet Chloë Grace Moretz plays an up-and-coming New York Post writer afflicted with a mysterious disease in “Brain on Fire,” an upcoming Netflix drama based on the memoir and real-life experiences of author and journalist Susannah Cahalan.

Chloë’s 21-year-old character is firing on all cylinders when the official trailer begins—her career in journalism is taking off, she’s smooching the man of her dreams, and she’s surrounded by friends, family, and colleagues who want nothing but the best for her. But everything changes after she wakes up ill one day.

“I feel really sick. You know, my head hurts, my stomach hurts, and my hand’s numb. I’ve never felt like this before,” she explains (above), shortly before passing out at work.

After enduring a barrage of medical tests, doctors still can’t identify what’s wrong with her. Some are even convinced the issues might all be in her head, but that’s a conclusion neither she nor her family are prepared to accept.

“Brain on Fire” is produced by Oscar-winning Stern Show guest Charlize Theron, among others, who acquired the rights to Cahalan’s novel “Brain on Fire: My Month of Madness” back in 2012. Adapted and directed by Irish filmmaker Gerard Barrett, the film co-stars Jenny Slate, Tyler Perry, and Carrie-Anne Moss.
