Just four weeks into its first season, FX’s Cold War drama The Americans has been picked up for a Season 2 with a 13-episode order. “The Americans has quickly established itself as a key part FX’s acclaimed drama line-up,” FX president John Landgraf said in a statement. Debuting on January 30, The Americans stars Matthew Rhys and Keri Russell as two sleeper KGB spies posing as Americans in suburban Washington D.C. in the early Eighties. The show premiered strong with 3.22 million viewers, bettering debuts by fellow FX series Sons of Anarchy and American Horror Story. Ratings for the second week initially saw a steep decline but Live +3 data brought the show’s viewership up to 3.11 million viewers. Former CIA agent and Falling Skies scribe Joe Weisberg created the series and exec produces with Joel Fields, Graham Yost and Amblin TV’s Justin Falvey and Darryl Frank for Fox TV Studios and FX Prods. The first season finale airs May 1.
