Homeland season five may shift its focus away from US political relations with the Middle East.

Showtime president David Nevins has stated that it's "a little bit up in the air" where Carrie Mathison and company find themselves next time around.

Speaking at the Television Critics Association press tour in Pasadena, he said: "We're not necessarily going to stay [with] US relations in the Muslim world.

"The real franchise of the show is how difficult it is to be America in the world in the 21st century - how difficult the choices are.

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

"I don't expect that show to fall into a formula. I can see it coming back to the US at some point."

According to Entertainment Weekly, Nevins also referenced the recent Paris attacks, noting that "it's a bit of a scary time to be a maker of controversial, political truth".

"It's been a bad month for free speech around the world," he said, before adding that he hopes the attacks won't prevent the show from tackling controversial issues.

"I hope [the attacks are] not considered at all," he said. "I really, really don't want there to be any limitations. I don't expect there will be. They never shied away from anything difficult. I want them to go right into the teeth of it again."
