The upcoming season of “Homeland” will feature two new recurring players, Variety has learned exclusively.

Sandrine Holt, known for her work in Netflix’s “House of Cards,” has joined the upcoming season of the Showtime series in a mystery role. She will appear in at least two episodes with the option for more. The network is keeping all details on her character under wraps, but insiders say her arc is very significant to the story.

Additionally, “Homeland” will also be bringing back Lesli Margherita for a recurring role in Season 7. The actress appeared in one episode last season, playing Sharon, who was a loyal character to Brett O’Keefe (Jake Weber).

No word yet on a premiere date for “Homeland” Season 7, though it’s likely to air during the first quarter of 2018. The Season 6 finale ended with the death of Peter Quinn (Rupert Friend) and President Keane (Elizabeth Marvel) offering Carrie (Claire Danes) a job as her senior adviser. Although Carrie is at first interested, she’s faced with a tough decision about whether she wants to continue working with Keane after Saul (Mandy Patinkin) and other high-level officials are arrested as a result of Keane’s paranoia.

Holt will next star in ABC’s upcoming drama “The Crossing.” She is also known for roles in “Mr. Robot,” “Hostages” and “The Returned.” She is repped by Innovative Artists and Management 360.

Margherita, who starred in Broadway’s “Matilda the Musical,” will next be seen in Netflix’s upcoming series “Seven Seconds.” She is repped by Stone Manners Salners and Velocity Entertainment Partners.
