The Paramount+ With Showtime drama The Agency is continuing to build up its cast.

Five actors — Alex Reznik, Andrew Brooke, Harriet Sansom Harris, India Fowler and Saura Lightfoot-Leon — have joined the espionage thriller, which stars Michael Fassbender and is based on the acclaimed French series Le Bureau des Legendes.

The cast also includes Jeffrey Wright, Jodie Turner-Smith, Katherine Waterston, John Magaro, and Richard Gere.

Currently filming in London, The Agency centers on Martian (Fassbender), “a covert CIA agent who’s ordered to abandon his undercover life and return to London station,” per the show’s logline. “When the love he left behind reappears, romance reignites. His career, his real identity and his mission are pitted against his heart; hurling them both into a deadly game of international intrigue and espionage.”

Reznik (Babylon) will play Coyote, an undercover CIA agent. Brooke (After Life, Children of Men) will play another CIA officer who goes by Grandpa.
