Homeland season 6 casts The Flash's Patrick Sabongui, Limitless actor Hill Harper

Just days before Homeland begins filming its sixth season in New York, two familiar faces have joined Showtime’s spy thriller.

EW has learned that Patrick Sabongui will be introduced as a CUNY law professor — and ardent advocate for the Muslim-American community — who works with Carrie (Claire Danes), while Hill Harper will play the chief of staff for U.S. president-elect Elizabeth Keane (House of Cards‘ Elizabeth Marvel).

Sabongui, who has a recurring role on The Flash and will appear in the new Power Rangers movie, also popped up on Arrow, Fringe, and 24. Harper, who recently starred in Limitless, was previously a cast member of Covert Affairs and CSI: NY.

Season 6, which debuts in January, will resume the action several months after the season 5 finale, with Carrie moving back to America and taking a job in New York at a foundation that offers aid to Muslims in the United States. The events of season 6 take place between Election Day and Keane’s inauguration.
