The Showtime pilot will star Damian Lewis as a US soldier seemingly planning a terrorist attack and Claire Danes as the CIA officer determined to prove his guilt.
Former 24 showrunner Gordon told TV Squad: "24 always had a kind of heightened reality. I think it had a nice emotional integrity, but always in a heightened kind of context. [Homeland] really does feel like it's happening in the real world, because it has that kind of slow, observational, very human storyline."
He described the pilot, which also stars Mandy Patinkin, Laura Fraser and David Harewood, as a "psychological thriller".
He suggested: "I think in some ways it's taking some of the same material [as 24] and looking at it in an entirely different way."
Gordon also compared the experience of working with Showtime to "the difference between... a major studio movie and [an] independent film".
"There's kind of a fearlessness there, to be nuanced and... to take your time," he explained. "The fact that there are no commercial breaks changes the rhythm and changes the whole experience. And of course, the latitude you have in terms of material."
The Homeland pilot is under consideration for Showtime's 2011-12 television season.
