I liked Sandra Oh in American Crime but would love to see her in a bigger role. Does she have any plans?

A: You’re in luck—and so is the former Grey’s Anatomy actress, who returns to TV as the star of the new BBC America drama Killing Eve (April 8). Based on the novellas by Luke Jennings, it’s about a slick psychopathic assassin (Jodie Comer) and the British MI5 security officer (Oh) charged with hunting her down. Oh, 46, says the “frazzledness” of Eve is what attracted her to the role.
