Margo Martindale, who won an Emmy for her role on FX's "Justified," is returning to the network on the new spy series "The Americans."

The show, which stars Matthew Rhys and Keri Russell  as an undercover KGB couple in Reagan-era America, premieres Jan. 30. Martindale has signed on to appear in at least eight episodes as “Claudia,” a KGB illegal who delivers assignments to the couple.

The casting reunites Martindale with "Justified" creator Graham Yost, an executive producer of "The Americans." Martindale won the Emmy Award for Outstanding Supporting Actress in a Drama Series for her performance as Mags Bennett on "Justified."

Since her exit from the show, Yost has talked about how much he misses working with the actress.

"What I do regret is just not having Margo on the show, in that she's such a tremendous actress and such a great person," he told TheWrap [5]. "That was the hard part."

Since leaving "Justified," Martindale has appeared on CBS's now-canceled "A Gifted Man" and has signed on for Showtime's "Masters of Sex."

"The Americans" was created by former CIA agent Joe Weisberg, who also executive produces. Besides Yost, it is also executive produced by Joel Fields and Amblin Television heads Justin Falvey and Darryl Frank. The series is produced by Fox Television Studios and FX Productions.
