Adapted from the comics by Greg Rucka, Gina Prince-Bythewood's "The Old Guard" follows a team of immortal mercenaries who can instantaneously heal themselves. For centuries, these warriors have used this ability to help civilians. However, they eventually find themselves as targets by pharmaceutical executive, Steven Merrick (played by Harry Melling, Dudley Dursley himself!), who goes after the group to torture them and capitalise on their powers. Leading the group and the fight against Merrick is Andy (Charlize Theron). Similar to the conflict between Voldemort and the group of young wizards, the tension between Andy's friends and Merric will totally give you "Order of the Phoenix" vibes.
