A Guide for the Married Man (1967)

Synopsis
Ed Stander (Robert Morse), with the help of an all-star cast, teaches Paul Manning (Walter Matthau) the fine art of philandering in A Guide for the Married Man. Paul, happily married to sexy Ruth (Inger Stevens), has no burning desire to cheat, but Ed makes the prospect sound very attractive. Finally taking the "big step" with a glamorous brunette after months of careful preparation, Paul finds that he loves his wife way too much to betray her -- while the ever-careful Ed ends up in divorce court. Among the myriad of "advisors" peppered throughout Guide for the Married Man are Art Carney, Lucille Ball, Jack Benny, Jayne Mansfield, Terry-Thomas, and Carl Reiner. The best guest-star vignette features Joey Bishop as a man caught in bed with another woman by his wife -- whereupon he calmly puts on his clothes, straightens up the room, and quietly responds to his wife's outrage by saying "What bed? What girl?" Adapted by Frank Tarloff from his book of the same name, Guide for the Married Man was directed by Gene Kelly, who makes a cameo "appearance" of his own as a voice on a TV set. ~ Hal Erickson, All Movie Guide
