Carrie-Anne Moss and Richard Armitage will join the cast of the indie drama “Brain on Fire” alongside Chloe Grace Moretz.

Moss and Armitage (“The Hobbit”) will play the parents of Moretz’s character. Jenny Slate and Thomas Mann also star in the film.

“Brain on Fire,” directed by Gerard Barrett (“Glassland”), is in production in Vancouver and slated for release in 2016.

“Brain on Fire” follows a rising journalist at the New York Post who mysteriously starts having seizures and hearing voices. As weeks go by, she moves inexplicably from violence to catatonia, but a last-minute intervention by one doctor finally gives her a diagnosis and hope to rebuild her life.

Broad Green Pictures is producing and financing the pic in partnership with Charlize Theron’s Denver and Delilah banner, along with Foundation Features.

Theron has been developing the project, based on Susannah Cahalan’s memoir “Brain on Fire: My Month of Madness,” since last year. Producers are Theron, A.J. Dix and Beth Kono of Denver and Delilah, along with Rob Merilees and Lindsay Macadam of Foundation Features.
