War Is Forever In 'The Old Guard' : Pop Culture Happy Hour The big summer action movie is one of the things we've been missing this year, and now, we've got one. And it's a good one, too. The Old Guard stars Charlize Theron and KiKi Layne as members of a squad of fighters who have been in the battle game for much, much too long. The Netflix film is based on a series of comics by Greg Rucka and Leandro Fernández, and Rucka wrote the screenplay. Director Gina Prince-Bythewood is much loved for films including Love and Basketball.
