BBC America will roll out its new original scripted series Killing Eve April 8, the network said during its Television Critics Association winter tour presentation.

The series, based on the Villanelle novellas by Luke Jennings, stars Sandra Oh (Grey’s Anatomy) an Jodie Comer (The White Princess) as two fiercely intelligent women -- a psychopathic assassin and the woman charged with hunting her down.

Series executive producer Phoebe Waller-Bridge said the Killing Eve offers a rare portrayal of two strong, female leads within a thriller series. “There is something glorious about a woman existing without fear or consequences of her actions," Waller-Bridge said.

The network also previewed its upcoming series Planet Earth: Blue Planet II, which debuts Jan. 20 and will be simulcast across BBC America, AMC, IFC, WE tv and SundanceTV. Blue Planet II narrator Sir David Attenborough said that the series provides an opportunity to show the beauty and majesty of the planet as well as the perils that it faces.
