Homeland is beefing up its roster. Still in production on season seven, with at least one notable vacancy to fill, the Showtime drama has cast actor James D'Arcy for a recurring part.

The actor is set to play Anson, an arrogant former special ops agent to who went to The Farm (the CIA's Camp Peary) with Carrie (Claire Danes).

D'Arcy's formal addition comes just a few days after Showtime released the first trailer for the new season of Homeland, one that again finds Carrie and Saul (Mandy Patinkin) at odds — with her working to expose presidential corruption and him taking a job in the Oval Office. (The series is currently in production in Richmond, Virginia.)

The actor, most recently seen in Christopher Nolan's WWII drama Dunkirk, has had prominent TV roles on Broadchurch and Agent Carter. He’s repped by WME, Management 360, and Markham Froggat & Irwin in the U.K.

Homeland returns Sunday, Feb. 11.
