Susannah Grant is the Oscar-nominated writer of “Erin Brockovich,” “Ever After,” "28 Days” and “In Her Shoes.” Her latest work is Netflix’s limited series “Unbelievable,” a docudrama adapted from reporting published by ProPublica and The Marshall Project that tells the story of two police detectives from different precincts who cracked the case of a serial rapist who carried out his vicious crimes in Colorado and Washington state between 2008 and 2011. Grant developed the project into an eight-episode depiction of both bungled and bravura police work. It’s also an essential analysis of the cold, systemic realities that victims of sexual assault often face when they make the courageous decision to report the crimes against them. In this episode of “The Call Sheet,” Grant talks about her efforts to avoid one-dimensional portraits of shoddy detective work, developing the look of the series as showrunner and collaborating with series stars Kaitlyn Dever, Toni Collette and Merritt Wever.
