William Jackson Harper Joins Hulu Legal Drama ‘Conviction’

EXCLUSIVE: William Jackson Harper (The Good Place) has joined the main cast of Conviction, Hulu‘s upcoming series starring Elisabeth Moss, from 20th Television.

Harper is set as a series regular in the legal drama alongside Moss, who also executive produces, and previously cast Jimmi Simpson, Kevin McKidd, Sebastian De Souza, Adam Godley, Linda Emond and Ella Anderson.

Written by House and The Good Doctor creator David Shore, Conviction follows criminal defense attorney Neve Harper (Moss), a confident lawyer who finally has her shot at a career-making case: a high-profile murder where the husband is accused of killing his wife by setting their home on fire. But when a mysterious stranger begins blackmailing Neve, she is forced to compromise every legal, moral, and ethical obligation to gain an acquittal — or else risk her dark secrets being exposed.

Details about the rest of the characters are not being revealed.

Conviction is based on the 2023 book of the same name by Jack Jordan who is executive producing alongside Shore and Erin Gunn via Shore Z Productions; Moss and Lindsey McManus via Love & Squalor Pictures; Warren Littlefield, Ann Johnson and Lisa Harrison via The Littlefield Co.; and Bert Salke via Co-Lab21.

Harper received an Emmy nomination in 2020 for his role as Chidi on NBC’s The Good Place and a Tony nomination in 2024 for his performance opposite Steve Carell in Anton Chekhov’s Uncle Vanya.

Coming off the fourth season of Apple TV+ series The Morning Show and Marvel’s Ant-Man and the Wasp: Quantumania, Harper will next be seen starring opposite Jon Hamm in the MGM+ series American Hostage. He recently completed production on the FX thriller limited series Cry Wolf, alongside Olivia Colman, and the indie film The Life and Deaths of Wilson Shedd, directed by Tim Blake Nelson.

Last summer, Harper starred in Not About Nightingales at the Williamston Theater Festival. He is repped by UTA, AC Management and Jackoway Austen Tyerman.
