I can't say too many good things about this extremely well done black comedy. The casting is first-rate, with Glenn Ford, Debbie Reynolds, and Carl Reiner. Glenn Ford is an underrated actor with a real flair for comedy, as shown here. Also of note is the fine bit by the venerable character actor John McGiver as Thorpe, the contractor. The plot keeps you going and the comic action never slips. I like also the decision to film it in black and white; it just looks right. As it is a wide-screen production, catching it in letterbox helps. A not-well-known film that is a nice comic surprise!
