Sandra Oh is officially returning to series regular television.

Two years after exiting ABC's Grey's Anatomy, the actress has booked the starring role in BBC America spy thriller series Killing Eve.

From Fleabag creator Phoebe Waller-Bridge, Killing Eve is a dramatic thriller that revolves around a psychopathic assassin and the woman charged with hunting her down. The eight-episode drama, picked up to series in November, will debut at a date to be determined in 2018.

Oh will take on the title role of Eve, a bored, whip-smart, pay-grade security services operative whose desk-bound job doesn't fulfill her fantasies of being a spy. Eve is pursued by Villanelle (uncast), an elegant, talented killer who clings to the luxuries her violent job affords her.  

Waller-Bridge, who earned raves for BBC U.K./Amazon's Fleabag, will serve as showrunner and exec producer. Sally Woodward Gentle and Lee Morris also exec produce the Sid Gentle Films drama that is based on the novellas by Luke Jennings.

"I am quivering with excitement about working with Sandra! I have been a huge fan of hers forever and am pinching myself that she is playing our Eve. She is going to be so badass in this role," Waller-Bridge said.

Killing Eve marks Oh's first series-regular role since the actress left ABC's Shonda Rhimes drama Grey's Anatomy following a 10-season run as Dr. Cristina Yang, a role for which she earned a Golden Globe, two SAG Awards and five Emmy nominations. Since exiting Grey's, Oh returned to ABC with a recurring role in John Ridley's anthology American Crime. On the feature side, Oh's credits include Sideways, Under the Tuscan Sun, The Princess Diaries and, more recently, Catfight.

Oh's casting marks a coup for BBC America as the actress continues to remain in high demand, fielding offers from broadcast networks, cablers and streaming outlets.

"Sandra Oh has the ability to go from wrenching to funny to total mess with a genius lightness of touch. Phoebe’s vision is absolutely original, and Sandra is utterly perfect casting we think for this key role," BBC America president Sarah Barnett said.

Oh is repped by UTA, Principal Entertainment and Hansen Jacobson.
