Catherine Keener

First Look Studios' Henry Winterstern and Kevin Turen are producing, in addition to Killer Films' Christine Vachon, Katie Roumel and Jocelyn Hayes-Simpson.

The story, which O'Haver wrote with Irene Turner, tells the true story of Sylvia Likens, a 16-year-old girl who died in 1965 while under the care of a woman named Gertrude Baniszewski. She put Sylvia through an ordeal that included beatings in the guise of discipline, burnings with cigarettes and matches and scalding hot baths, among other tortures. Encouraging a "Lord of the Flies"-type cult, Baniszewski involved her own children and children from her Indianapolis neighborhood in the punishments.

Keener is playing Baniszewski, while Page plays Likens.
