Based on the comic series of the same name by writer Greg Rucka and artists Leandro Fernández, the plot centers on a group of immortals who have spent their thousands of years of life on Earth trying to do as much good as they can for the world. It makes for a hard, secretive life, but things get even harder when, almost simultaneously, a new immortal wakes up in the world, and the group is set up by an ex-CIA agent. The impressive cast includes Charlize Theron, KiKi Layne, Matthias Schoenaerts, Luca Marinelli, Marwan Kenzari, Harry Melling, and Chiwetel Ejiofor, and the release was met by acclaim from both critics and audiences alike.
