Based on the memoir by Jeannette Walls, the film stars Brie Larson chronicles the life of a successful New York-based journalist all the way back to her poverty-filled childhood, with Woody Harrelson and Naomi Watts playing her parents.

The Glass Castle is set for release on August 11. But the film will also tell a true story about a very real - and very compelling - woman: Jeannette Walls, who penned the 2005 memoir of the same name from which The Glass Castle is adapted.
