We've known for some time that Showtime drama 'Homeland' would undergo something of a renaissance in season 4, and while we won't see any fresh episodes until September, the first new cast members have arrived. 'House of Cards' breakout and 'The Strain' star Corey Stoll has been added to the recurring cast, along with Laila Robins as a new series regular.

According to Showtime, Robins' series regular role will see her playing Martha Boyd, the US Ambassador to the Islamic Republic of Pakistan, described as professional and put together, with a ship-to-ship voice and the personality to match. Stoll will portray Sandy Bachman, appearing in a number of episodes as the CIA Chief of Station in Pakistan and a rising star in the agency's firmament.

Elsewhere, relatively little is known of the fourth season of Showtime’s Emmy-winning drama, though past series regulars Morena Baccarin and Morgan Saylor will have understandably reduced (if not entirely omitted) presences in season 4, while Nazanin Boniadi’s Fara has been upped to regular. Mandy Patinkin’s Saul Berenson and Rupert Friend’s Peter Quinn have been confirmed to return, as well, while season 4 will return to the character’s roots as a competent case officer in a foreign country. Additionally, acclaimed scribe Meredith Stiehm will return to the writer’s room full time, having been minimally present in season 3 to work on FX drama ‘The Bridge.’

It's a shame 'Homeland' couldn't hold onto Stoll for longer than a recurring role, but in the meantime, what say you? Does 'Homeland' season 4 look to be shaping up from the past few seasons?
