Netflix and Skydance have released a new  The Old Guard trailer for the upcoming action film, which puts a twist on a traditional formula. Based on the graphic novel series of the same name by Greg Rucka and Leandro Fernandez and scripted by Rucka himself, the film follows a warrior named Andy (Charlize Theron) and her covert group of tight-knit mercenaries who are, by all intents and purposes, immortal. And they have been for a long time—snippets of footage show them fighting throughout the ages. But when their extraordinary abilities are exposed and under threat, they must go on the run all the while training their newest recruit Nile (KiKi Layne).
