SERIES PREMIERE: You can’t blame FX for cashing in on its increasingly relevant period drama series The Americans, which features a pair of Russian secret agents working undercover as everyday Americans in Ronald Reagan’s Cold War 1980s. But rather than present a dramatic reversal, with American spies pretending to be everyday Soviets, FX is going the comic route. In this period sitcom set in the 1960s, Dave Thomas and Sally Kellerman play bumbling American secret agents tasked with infiltrating the U.S.S.R. by posing as everyday Soviet citizens. The problem, and the alleged humor, comes from the fact that these spies base their cover identities entirely on the pop-culture spies they’ve seen on movies and TV – starting with Boris and Natasha from The Bullwinkle Show.
