The '80s-set project - from Graham Yost (Justified) and Joe Weisberg (Falling Skies) - will focus on two Cold War KGB spies who pose as a married American couple.
Keri Russell (Mission: Impossible III) will play wife Elizabeth, while Matthew Rhys (Brothers & Sisters) was recently cast as her 'husband' Phillip.
Emmerich - who recently appeared as Dr. Edwin Jenner on The Walking Dead - will play the couple's new neighbour, reports Deadline.
An FBI agent working in Counter Intelligence, Emmerich's character becomes suspicious of Elizabeth (Russell) and Phillip (Rhys).
Emmerich's recent credits include films such as Warrior and Super 8, as well as web-series Backwash.
