If he hadn't already used that title for another movie, Tom Cruise could have easily called 'Jack Reacher' 'The Last Samurai.' There's a bit of Toshiro Mifune's Sanjuro in this Reacher guy: the masterless warrior who strides into a corrupt town, answers to no one, rights a few wrongs, busts a few heads, and wanders away to find his next challenge. He has no possessions; he owns exactly two shirts and one jacket. All he carries with him is a roll of $100 bills, a passport, a toothbrush, and his inflexible moral code. He would have fit right in back in feudal Japan. Or the Old West, for that matter. He'd make a hell of a Man With No Name.
