No, despite the title, it’s not a Scanners-style sci-fi thriller. Brain On Fire has been adapted from Susannah Cahalan’s memoir, which was subtitled My Month Of Madness. The book chronicles Cahalan’s real-life experiences being diagnosed with a mystery illness that left her labelled psychotic, violent, and a dangerous flight risk. She woke up alone in a hospital room confined to the bed, unable to speak or move and with no memory of what happened. In the maelstrom, she’d lost everything: a promising newspaper career and her first serious relationship, and it took a lot of strength and the support of her family to get through it.
Thomas Mann is aboard to co-star in the film, which Barrett wrote and has Charlize Theron producing. Who, perhaps not so coincidentally, co-stars with Moretz in Gillian Flynn adaptation Dark Places, which is out in the US on August 7 but doesn’t yet have a UK date. Over here, the young actress will next be seen in sci-fi adaptation The 5th Wave, which arrives on January 29.
