The Newsroom alum Alison Pill has signed on to the untitled ABC/ABC Studios drama pilot written by Jenna Bans and directed by Paul McGuigan. It follows the return of a politician’s (Joan Allen) young son, Adam Warren (Liam James), who was presumed dead after disappearing over a decade earlier. But as the mysterious young man is welcomed back into his community, the neighbor sitting in jail for his murder is released and the cop responsible is forced to re-examine what truly happened so many years ago. CAA-repped Pill plays Willa Warren, Claire (Allen) and Peter’s daughter, and her mother’s campaign manager. Willa lost the twinkle in her eye many years ago when her little brother went missing. She feels responsible for his disappearance, as she was with him when he vanished.
