Nazanin Boniadi in the Espionage Counterpart

 Counterpart, premiering Jan. 21, begins with an assassin crossing over from one dimension to the other and then time is of the essence to track her down to prevent a tragedy. To do so, Howard Silk (J.K. Simmons), normally a lowly cog at the agency, is called into the action, and for the first time in his life, becomes aware that there is another Howard on the other side, whose life parallels his but has taken a different turn.
