Chapter One: Don’t do it. Such might be the expected opening salvo when perusing A Guide for the Married Man (1967), but that would be too easy. Though this breezy and amoral goof on connubial warfare comes from an era when a fictional movie couple was expected to sleep in separate beds, the film’s advice to real-life grooms is progressive and valuable even today. A rakish young husband explains the secrets of cheating on the wife without her finding out. These priceless life’s lessons are presented in vignette form, with each self-contained mini-story being acted out by high-profile stars of the day. As the esoteric knowledge is revealed, a longtime faithful mate prepares for his first foray into infidelity. Which is more aquiver: The would-be Casanova’s moral compass? Or the flick’s swinging ’60s soundtrack?
