Homeland” has recruited four new series regulars to join Claire Danes’ reckless CIA agent Carrie Mathisen on her missions.

The Showtime drama welcomes Miranda Otto, Sebastian Koch, Sarah Sokolovic and Alexander Fehling as series regulars in the upcoming Berlin-set fifth season.

Picking up two years after her ill-fated tenure as Islamabad station chief, the new season finds Carrie estranged from the CIA and working for a private security firm in Germany. But it sounds like Carrie can’t escape her past: Otto plays current Berlin Chief of Station Allison Carr, who is working directly under Carrie’s CIA mentor, Saul Berenson (Mandy Patinkin).

Other casting details were equally vague. Koch plays Otto Düring, a German philanthropist with an eponymous foundation and Carrie’s boss. Sokolovic plays Laura Sutton, an American journalist who works with Carrie. Fehling plays Jonas Happich, legal counsel for the Düring Foundation and Carrie’s boyfriend.

Showtime also confirmed that Rupert Friend, whose character of Peter Quinn was last seen flying off to an almost-certain suicide mission, will be returning to the series.

Season five of “Homeland” begins filming this week in Berlin, where German film and TV fund Medienboard just contributed $1.1 million to the cost of shooting. The 12-episode season will premiere this fall on Showtime.

Produced by Fox 21 Television Studios, “Homeland” was developed for American television by Alex Gansa and Howard Gordon. It’s based on the original Israeli series “Prisoners of War” by Gideon Raff. Along with Gansa, Gordon and Raff, the executive producers for season five are Alexander Cary, Chip Johannessen, Meredith Stiehm, Patrick Harbinson, Lesli Linka Glatter, Avi Nir and Ran Telem.
