Armstrong, a recurring cast member on Showtime's "House of Lies" and a veteran of "One Tree Hill," has signed on for the ABC drama pilot "Reckless."
The pilot, written by Chris Black ("Red Widow," "Mad Men") revolves around David, who's forced to consider less-than-legal options after his wife is unjustly imprisoned during a political uprising overseas and the U.S. government thwarts his efforts to have her released out of diplomatic concerns.
Armstrong will play Catherine, the mother of Sara, David's kidnapped wife.
"Almost Famous" star Patrick Fugit is cast in the role of David. The cast also includes Ashton Holmes ("Revenge") and Lou Taylor Pucci.
Martin Campbell ("Casino Royale") is directing and executive producing the pilot.
