Sandra Oh had reached household name status with her role in ABC’s Grey’s Anatomy, but it was arguably her follow-up that was her magnum opus. After retiring from the medical drama after 10 seasons, she eventually went on to star in a much different story. Killing Eve was a BBC America series, adapted from Luke Jennings’ series of books, Codename Villanelle. At the time, Oh reported that she was surprised to be tapped for the project, since she assumed that a woman of color would not be the choice for the titular role. Instead, she gave the gift of an obsessed MI6 agent in over her head.
