2020’s The Old Guard was directed by Gina Prince-Bythewood and written by Greg Rucka, who also wrote the comic book of the same name (the film is based on the comic). The film stars Charlize Theron, KiKi Layne, Matthias Schoenaerts, Marwan Kenzari, Luca Marinelli, and Chiwetel Ejiofor.
The promising career of American Marine Nile Freeman (KiKi Layne) comes to a sudden and tragic end when the wounded Afghan insurgent whose life she is attempting to save  slits her throat. Nile bleeds to death in moments; her demise is a grim lesson in the cost of inattention.
Much to Nile’s surprise, and the surprise of those around her, this is not the end of her story.
