The Old Guard trailer

Charlize Theron is an immortal warrior. Also, The Old Guard is coming soon, based on the comics by Greg Rucka and Leandro Fernandez, and looking like a guns-y group-game-friendlier Highlander facing modern weird-hunting agents like Vampire: The Masquerade’s Second Inquisition.

Edit having seen it: it plays the immortal warrior in a very grounded international espionage way rather than the epic fantasy take seen in Highlander, so while they have melee weapons they use them as well as guns in gunfights rather than haveing swordfights with anyone else and theres a distinct lack of indoor thunderstorms.
