'Homeland' will undergo something of a metamorphosis in its fourth season, shifting from the story of Carrie Mathison (Claire Danes) and Nicholas Brody (Damian Lewis) to a more generalized tale of an intelligence officer in a foreign country. We've seen one trailer to date, but the newest look at 'Homeland' season 4 gives off a much better look at the ensemble, promising a two-hour premiere to remember.

"It hasn't been a fourteen-year war we've been waging, but a one-year war waged 14 times," corrects Saul in the newest footage from 'Homeland' season 4, set to a haunting rendition of Emily Jane White's "Hole in the Middle." We also learn that Carrie's decision to work abroad may not be so beyond choice as she'd have us believe, unlike the bitter Quinn. Elsewhere, Corey Stoll continually looks gruff without his ridiculous wig, and why shouldn't he?

Previously, showrunner Alex Gansa spoke to what season 4 of 'Homeland' will focus on:

[Season 4] is about seeing Carrie Mathison for the first time doing the job she was trained to do — being a case officer in a foreign capital. We’re going to see what an intelligence officer does on the ground. How she recruits assets, how she deals with the foreign government and her country team — the people she works with in the embassy — and the host country’s intelligence services. That is a complicated and murky world, one that we hope is filled with intrigue and drama and adventure.

The whole reason we chose this part of the world is that American forces are drawing down in Afghanistan. So the question is: What were we doing there for 14 years? When we leave is the Taliban just going to swoop back in and take the country over? What was all the blood and treasure spent worth? And when the military does draw down, who’s left behind? People like Carrie Mathison and Martha Boyd (Laila Robins) — the CIA and the State Department people are the ones left on the ground when the military leaves, and it’s up to them to try and keep that country intact. Carrie’s on the ground in a dangerous place trying to break the law which puts her in a very charged situation.

Elsewhere, we know of season 4 that past series regulars Morena Baccarin and Morgan Saylor will have understandably reduced (read: no) presences in season 4, while Nazanin Boniadi’s Fara has been upped to regular. New additions also include Laila Robins,' 'Life of Pi' star Suraj Sharma, 'Smash''s Raza Jaffrey and Michael O'Keefe. 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.’

'Homeland' season 4 will premiere Sunday, October 5 with two all-new episodes, but what do you think? Does the latest moody trailer promise that season 4 will prove the most dramatically rich yet?
