Simultaneously a tough guy and a sap, a realist and a romantic, director Michael Mann has for decades now been making movies about what it means to be a man. He chooses to tell these stories in familiar settings, setting his fairly measured character studies in the kind of testosterone-soaked milieu that has been favored by a century of manly filmmakers. Mann has made movies about cops and robbers. There’s one about a cab driver and an assassin, one about a whistleblower and another about a great athlete. He’s even made a supernatural horror movie set among Nazis. But he keeps returning to the subject of heroes and villains, about the role-playing that takes place when good guys go head-to-head with bad guys, and about what happens when the line between antagonist and protagonist gets blurred.
