O'Sullivan Charts "The Secret Scripture"

Thaddeus O'Sullivan ("Into the Storm" "The Heart of Me") is set to direct an adaptation of author Sebastian Barry's award-wining novel "The Secret Scripture" says THR.

The Ireland-centric story concerns a 100-year old Presbyterian woman who has been in a mental hospital since World War II. 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.

Jessica Chastain and Vanessa Redgrave will play older and younger versions of the woman.

Noel Pearson will produce the film
