Kathryn Hahn, the female lead of NBC’s short-lived comedy series Free Agents, is staying at the network with a four-episode arc on Parks and Recreation. She will play the campaign manager of Amy’s (Amy Poehler) opposition in the election. Hahn is repped by Gersh and Brillstein Entertainment.

Nora Zehetner is set to recur on another series, USA’s upcoming buddy-cop dramedy Common Law, about butting detectives Travis (Michael Ealy) and Wes (Warren Kole) ordered to attend couples therapy. She will play a pretty and offbeat female detective fresh out of training at Quantico and the new head of the digital technology unit. She’s immune to Travis’ flirty charms but is impressed by Wes. Zehetner, repped by APA and the Schiff Co, has recurred on Grey’s Anatomy, Mad Men and Heroes.
