Speaking to TV Squad, Doug Liman explained that the series examines the everyday experiences of CIA agents.
He explained: "Just because you're a spy doesn't mean you don't have to pay taxes, or that you're not the one having to take the lunch order because you're the newest employee."
Liman also suggested that the characters' romantic lives will be examined on the show.
"[Our consultant] Valerie told us that they were encouraged to date within the Agency," he said. "That's very much part of our show. But it actually happens to be the reality of working at the CIA. The divorce rate for people who marry outside the agency is very high."
Covert Affairs, which stars Piper Perabo, Chris Gorham and Peter Gallagher, premieres on July 13 at 10pm on USA.
