I'm actually tempted to get Netflix just for this film. It sounds amazing.

The scenes where Sarah Lancashire and Keira Knightley face off are really something to behold – two phenomenal actors at the height of their game bouncing off one another with ample room to really flex their talents.

Usually one for a period drama, Knightley is as you've never really seen her before. Splattered in blood and not too shy to wield a kitchen knife, her no-nonsense character Helen perfectly straddles the two worlds of doting mother and fearless spy. This is keenly illustrated in one of the first moments we see her in action on screen, warding off some baddies like it was a casual Wednesday-evening activity while taking a FaceTime from her daughter who is struggling to sleep.
