Hulu has added four new cast members to the upcoming legal drama series “Conviction.”

Variety has learned exclusively that Linda Emond has been cast in a series regular role, while Zainab Jah, Ashley Zukerman and Jose Zúñiga have all joined in recurring guest star roles. The new additions join previously announced lead Elisabeth Moss as well as fellow cast members Jimmi Simpson, Sebastian De Souza, and Adam Godley.

The show is based on the Jack Jordan novel of the same name and was greenlit at the streamer in February.

The logline for “Conviction” states, “Criminal Defense Attorney Neve Harper (Moss), a confident lawyer, 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.”

Exact character details aside from Moss’ are being kept under wraps.

Emond’s past TV credits include “The Gilded Age,” “The Patient,” “Only Murders in the Building,” “Madam Secretary,” and “The Good Wife” as well as “The Good Fight.” She has also been in films like “Across the Universe,” “City by the Sea,” “North Country,” and “Causeway.” Emond is a three-time Tony Award nominee and currently stars in the Broadway play “Becky Shaw.”

Jah recently appeared in the John Wick spinoff series “The Continental” as well as films like “Drift” and “All Dirt Roads Taste of Salt.” She has appeared in TV shows like “Only Murders in the Building,” “The Good Lord Bird,” and “Homeland.”

Zukerman has starred in shows such as “Manhattan” and “The Lost Symbol” while he has also had roles in shows like “Succession” and “Designated Survivor.” He also appeared in the Apple show “Silo,” with the third season of that series due out in July. In film, he has starred in all three films in the “Fear Street” franchise.

Zúñiga has been seen in series like “Narcos: Mexico,” “Griselda,” “Westworld,” “CSI,” and “Physical.” In film, he is known for features like “Sound of Freedom,” “The Life List,” and “Alone at Dawn.”

Emond is repped by CAA. Jah is repped by IAG and Rob Kolker Management. Zukerman is repped by Gersh, EMG, and Lisa Mann Creative Management. Zúñiga is repped by SBD Partners and Prime Talent Media.

Moss is also executive producing under her Love & Squalor Pictures banner in addition to starring.
