Kiernan Shipka Flowers in the Attic CastAnd you thought Sally Draper was a messed-up little girl…

Mad Men‘s Kiernan Shipka has been cast as the young female lead in Lifetime’s upcoming adaptation of V.C. Andrews’ novel Flowers in the Attic, our sister site Deadline reports.

The eerie made-for-TV movie will tell the story of Corrine (played by Heather Graham, Scrubs), a recent widow who puts her four children into a pretty terrible situation at her parents’ mansion after their father’s death. A disturbing family secret causes the children’s grandmother, Olivia (Ellen Burstyn, Political Animals) to lock the children in the attic, where the oldest boy and girl (Shipka) develop a really-not-OK bond.

Mason Dye (The Secret Diary of an American Cheerleader Web series) has been cast as Shipka’s character’s brother.

Shipka has played Don and Betty Draper’s daughter Sally since the AMC series’ first season, and she has appeared on Monk and Heroes. She also played herself in a 2012 episode of Don’t Trust the B—- in Apartment 23.
