Former Grey’s Anatomy star Sandra Oh has landed the lead role in a new BBC America thriller called Killing Eve.

Based on the novellas by Luke Jennings, Killing Eve focuses on two fiercely intelligent women: a psychopathic assassin named Villanelle and a bored, desk-bound security operative named Eve (Oh), who’s sent into the field to hunt down Villanelle.

Phoebe Waller-Bridge, who created, wrote and starred in last year's acclaimed BBC comedy Fleabag, will write the eight-episode run, which is set to debut next year. She will be the Killing Eve showrunner.

This is Oh’s first regular role since leaving Grey’s Anatomy in 2014. While there she earned five Emmy nominations and a Golden Globe for her performances as Dr Cristina Yang.

More recently, she played a recurring role in the third and final season of ABC’s American Crime.

"Sandra Oh has the ability to go from wrenching to funny to total mess with a genius lightness of touch," BBC America president Sarah Barnett said in a statement.

"Phoebe [Waller-Bridge]’s vision is absolutely original, and Sandra is utterly perfect casting, we think, for this key role."
