Adapted by Norman Krasna from his play Kind Sir, Indiscreet stars Ingrid Bergman as a wealthy actress and Cary Grant as an international financial wizard. While Grant is visiting London, Bergman's sister Phyllis Calvert and brother-in-law Cecil Parker introduce Grant to Bergman. Because he feels he has no time for marriage, Grant pretends to be married to avoid romantic tangles. Bergman, however, finds the prospect of an affair with a married man to be quite exhilarating. When she discovers the truth, Bergman gets even with the now-smitten Grant by faking a romance with an ex-boy friend--ordering luckless chauffeur David Kossoff to pose as her beau. A comedy by grownups, about grownups and for grownups (at least by 1958 standards), Indiscreet proved to be far more successful as a film than as a stage play.
