'Brain on Fire' is a 2016 American-Canadian-Irish biographical drama film directed and written by Gerard Barrett.

After a series of tantrums, misdiagnoses, and a lengthy hospital stay, a doctor's last-minute intervention enables him to give her a diagnosis and a chance to rebuild her life.

The film stars Chloë Grace Moretz, Jenny Slate, Thomas Mann, Tyler Perry, Carrie-Anne Moss, and Richard Armitage.

Brain on Fire first premiered at the Toronto International Film Festival in 2016.
