Thaddeus O'Sullivan ("Into the Storm"," "The Heart of Me") is set to direct an adaptation of the award-wining Sebastian Barry novel "The Secret Scripture" for Voltage Pictures.
Jessica Chastain and Vanessa Redgrave are attached to star in the Ireland-centric story about a 100-year old Presbyterian woman who has been in a mental hospital since World War Two.
With the facility closing, a psychiatrist tries to piece together why the woman is there, not knowing she has been hiding a diary under the floorboards detailing her harsh treatment both during Ireland's civil war and at the hands of an abusive priest.
Chastain and Redgrave will play older and younger versions of the woman. Noel Pearson will produce.
