Cold War drama “The Americans” is off to a fairly hot start for FX.

Wednesday’s premiere of the series about Soviet spies living in plain sign in the early days of the Reagan adminstration averaged 3.22 million viewers overall, including 1.57 million adults 18-49. This is a larger overall audience than the premiere of “American Horror Story” (3.18 million) in total viewers and larger than “Sons of Anarchy” (1.55 million) in the demo.

If you add in the show’s two encore telecasts to air following the premiere, “The Americans” averaged a combined 4.7 million viewers and 2.54 million adults 18-49.

Competitively in the 10 p.m. hour, “The Americans” beat out a repeat of ABC’s “Nashville” and trailed CBS’ “CSI” repeat and NBC’s original “Chicago Fire.” The FX skein topped those broadcast shows in men 18-34 (407,000).

“The Americans,” from Fox Television Studios and FX Prods., stars Keri Russell and Matthew Rhys. Executive producers are Joe Weisberg, Joel Fields, Graham Yost, Justin Falvey, Darryl Frank and Gavin O’Connor.

Topping “The Americans” and all of cable Wednesday was Discovery’s second-season finale of “Moonshiners” (1.7/5 in 18-49, 3.87 million viewers overall), which set series highs. It ranked second on all of television for the night (behind “American Idol”) in men 18-49 (2.2/6) and men 25-54 (2.6/6).
