One of the failings of the movie industry is that Paul Scofield has not been hired for enough jobs. This has been a blessing for the British theater, of course, but it would be pleasant to have more of his roles recorded. Fortunately he appeared in this and a few other BBC TV productions and while Noel Coward's comedies of manners have not aged well, Scofield shows up well, starting out as an annoying individual in the first act but coming into clear and amusing focus the second act.
One of the weaknesses of this piece is the way he and Toby Robins have been directed. While Scofield puts on a fairly convincing Texan accent, Ms. Robins talks like a middle-class Jew from Brooklyn -- and the two of them are supposed to have known each other all their lives. This is a fairly typical and old-fashioned bit of British snobbery among uncareful directors: look at the way Americans behave in Agatha Christie pieces from the 1930.
