Carrie-Anne Moss and Richard Armitage have joined the cast of Broad Green Pictures drama Brain on Fire.

Based on Susannah Cahalan’s memoir Brain on Fire: My Month of Madness, the drama is currently in production in Vancouver.

Chloë Grace Moretz (Kick-Ass) is set to play Cahalan while Moss (The Matrix) and Armitage (The Hobbit) will play Susannah’s parents, Tom Cahalan and Rhona Nack.

Gerard Barrett (Glassland) will direct while Charlize Theron, A.J. Dix and Beth Kono of Denver & Delilah, and Rob Merilees and Lindsay Macadam of Foundation Features are producing.

Director of Photography is Yaron Orbach (She’s Funny That Way), production designer is Ross Dempster (Seventh Son), and art director will be Erin Sinclair (Man of Steel). Costume designer is Farnaz Khaki-Sadigh (The Flash) and editor is Justin Li (Nash).

Brain on Fire follows Susannah Cahalan, a rising journalist at the New York Post who mysteriously starts having seizures and hearing voices. As weeks go by she rapidly descends into insanity and moves inexplicably from violence to catatonia.

Following a series of outbursts, misdiagnoses and a prolonged hospital stay, a lucky last-minute intervention by one doctor finally gives her a diagnosis and hope to rebuild her life.

Mister Smith Entertainment handles international sales. Broad Green will release in the US. Release is due in 2016.
