While Showtime's Homeland has dealt pretty exclusively in the Middle East for its first four seasons, it may not be this way forever.

'Homeland' Showrunner Talks Carrie's 'Controversial' Bathtub Scene, "She Is A Danger To Her Own Child"

Much of the hook of Homeland has been in the conflict between the U.S. and the Middle East and its resonance with modern times. However, Showtime president David Nevins appeared at the Television Critics Association press tour on Monday where he said that conflicts with other countries and cultures are possible as Homeland moves forward.

"I don't expect that show will ever fall into a formula. I can see it coming back to the U.S. at some point," Nevins said, via Zap2It. "It worked very well this year to say this is the franchise of the show -- Carrie Mathison [Claire Danes], a skilled but complicated intelligence operative dealing with real stuff on the ground. I expect that we'll go back to that this year."

He observed that ultimately the through line of the show is "how difficult it is to be America in the world in the 21st century," just in general.

"I think that's the story that will remain relevant as long as they can come up with new stories -- could be Africa, could be Europe, could be back in another place in the Middle East."

He also teased that the ghost of Brody (Damian Lewis) may continue into the future now that they have the device of Carrie's hallucinations of him.

Homeland returns for season 5 in fall 2015 on Showtime, though the network has not yet announced a specific premiere date.
