The Philco Television Playhouse S01E01 - Dinner at Eight

Social-climbing Mrs. Oliver Jordan, whose husband's firm is in financial trouble, feels obligated to reciprocate hospitality for a visiting British aristocratic couple by arranging a small dinner party. The guests are chosen both to impress--a faded stage star, a well-known if over-the-hill alcoholic actor --and to meet certain social obligations. This means the necessary inclusion of a philandering doctor and his wife, and a gauche, nouveau-riche couple who are loathed but powerful.
