Walter Matthau is Henry Graham, an aging playboy used to high and fine living who suddenly finds himself destitute. What to do? The only solution, according to Henry's Butler, is to marry a wealthy woman, except Henry is a confirmed misogynist, so the idea revolts him. Then he adds his own twist - he will marry the woman, get her money, and then murder her. His quest for the perfect victim leads him to Elaine May, as Henrietta, an extravagantly clumsy and extravagantly wealthy botanist who seems the perfect foil for Henry's scheme.

This is a perfectly cast movie. Even the supporting players, such as James Coco and William Redfield, on screen a few minutes, are hilarious. Matthau has never been better or funnier. Pure exasperated snobbishness hasn't been so exquisitely embodied since W.C. Fields groaned and grimaced his way through 1930's American comedy.
