There’s been a long stream of movies featuring Liam Neeson in aging action star mode that began with Taken back in 2008, and the actor is still going strong. The latest in this ongoing career arc is The Marksman, which finds the actor playing an ex-Marine sharpshooter just trying to get by on an isolated stretch of borderland. But when a young immigrant child on the run ends up in his care, he takes it upon himself to fend off the drug cartel assassins who are on his trail.
