The highly anticipated spy drama The Americans makes its debut tomorrow night on FX at 10 p.m. The Cold War series focuses on a pair of KGB spies living as a married couple in Washington D.C. during the early 1980s. The 12x1-hour show, from creator and executive producer Joe Weisberg (Falling Skies, Damages), is co-produced by Fox Television Studios and FX Productions. It is being sold worldwide by Twentieth Century Fox Television Distribution, which just scored a slot for the series in the U.K., where it will launch on ITV. In this video interview, The Americans’ co-stars Matthew Rhys (Brothers & Sisters) and Golden Globe-winner Keri Russell (Felicity) sit down with World Screen's Anna Carugati to discuss what appealed to them about the show. They also talk about their characters’ complex relationship with one another, and how it affects their undercover mission.
