EXCLUSIVE: David Manson has come on board AMC’s LaGravenese & Goldwyn pilot (aka Philly Lawyer) as executive producer/showrunner. The untitled project is a legal thriller centered on a District Attorney who uncovers new evidence that prompts the reinvestigation of a sensational murder case. It explores personal morality and how people struggle with the shades of grey found in the absence of a simple, ordered moral universe. Feature scribe LaGravenese wrote the script and will executive produce the pilot with Goldwyn, who will direct, and Mason. Andrew Sugerman will serve as a co-executive producer. Manson most recently served as executive producer/co-showrunner of the FX drama pilot Outlaw Country. His credits also include New Amsterdam and Thief. Additionally, Manson created/exec produced the TNT series Saved. The untitled LaGravenese/Goldwyn project is one of two drama pilots AMC picked up last month, along with Low Winter Sun.
