When 20th Century Fox entered TV in the 1950s, one of the programs was an hour-long anthology series. This series took many Fox classics (THE GHOST AND MRS. MUIR, HOUSE OF STRANGERS, MIRACLE ON 34th STREET, THE LATE GEORGE APLEY, YOUNG MR. LINCOLN, et al) and reduced them to less-than-an-hour. One of the entries in that series was titled DECEPTION, and it starred Linda Darnell and Trevor Howard; it was about a woman intelligence officer in charge of a complicated spy mission: she has to pick a man who will turn out to be a coward, so that he can be given false information which he will divulge (under torture) to the Nazis. Unless i'm very much mistaken, this is one instance when the TV episode was embellished into a feature film (made in 1961). The movie provides a lot more exposition, but the story is the same, including the female intelligence officer seeking out the man after the war. This film stars Suzy Parker as the intelligence agent, and Bradford Dillman as the man; soon after this movie, they would marry and she would retire from acting. Though they don't have the same depth as Darnell (an exceptional performance) and Howard, Parker and Dillman are nevertheless quite a glamorous couple (as they were in real life).
(Though the film is well-done, the TV show, in this instance, packed more of a punch, and the performances of Linda Darnell and Trevor Howard were exceptional.)
