Waller-Bridge, hot off the success of her Amazon show Fleabag, penned the eight-episode spy thriller for BBC America. According to the network, the show “centers on two women; Eve is a bored, whip-smart, pay-grade security services operative whose desk-bound job doesn’t fulfill her fantasies of being a spy. Villanelle is an elegant, talented killer who clings to the luxuries her violent job affords her.” Oh will play Eve, and Villanelle is yet to be cast. Waller-Bridge will serve as showrunner and executive producer on the project.
