EXCLUSIVE: The Beautiful Lie star Sarah Snook is in negotiations to appear in Lionsgate’s The Glass Castle, the Destin Daniel Cretton-directed adaptation of the best-selling memoir by Jeannette Walls.

Like the book, the film will chart Wall’s dysfunctional, impoverished upbringing in the American Southwest and its impact on her later writing career; the deal isn’t done yet, but Snook would play Walls’ sister opposite Brie Larson as glasscastleWalls, with Naomi Watt and Woody Harrelson as their parents. Cretton is writing the script with Andrew Lanham and Marti Noxon; Erik Feig and Gil Netter are producing. The Glass Castle is another potential hit for Lionsgate that’s based on successful IP – the book spent 261 weeks on the New York Times best sellers list and went on to sell nearly 3 million copies.

Snook recently starred in the Old Vic production of The Master Builder alongside Ralph Feinnes, and held the lead role in ABC’s 6-part miniseries The Beautiful Lie. Other credits include Steve Jobs, The Dressmaker opposite Kate Winslet and Liam Hemsworth, Holding The Man with Guy Pierce and Geoffrey Rush, the ABC pilot Clementine, and the Robert Heinlein adaptation Predestination with Ethan Hawke and Noah Taylor. She’s repped by UTA, Jenny Rawlings, and Shanahan Management.
