This is a very entertaining artifact of its era, the swinging sixties.Concerning the attempts of Walter Matthau to cheat on his sexy wife Inger Stevens with the even more sexy and luscious Sue Ann Langdon (what did this guy want, everything?)cheered on by his rake of a pal, Robert Morse(!!). A case of stunt casting which in this case works. The sexual revolution hits poor suburbanite Matthau right in the face and he wants in on it. Who can blame him? This would-be bawdy comedy was directed by nice guy Gene Kelly, so if it's not rapacious enough for some, it's still the best piece of bawd this side of Billy Wilder.
