The Old Guard was released on July 10th this year and has become one of the most popular original films streaming on Netflix this month. Adapted from a graphic novel series by Greg Rucka and Leandro Fernandez that was first published in 2017, The Old Guard follows a group of expert, world-weary (and refreshingly diverse) mercenaries who travel the globe killing terrorists, hiding their identities, and speculating on immortality (hinting at this film's gold mine twist).
