Night Editor was based on the already existing radio program in which a newspaper editor would recount the ‘inside story’ of some bit newspaper story, and later became a television series: This time, a night editor of a newspaper is telling a story to a young reporter, who is neglecting his job and wife and beginning to drink too much. The story begins as a police detective, although devoted to his wife and young son, has entered into an affair with a society girl, also married, and while they are parked out in the boonies on a lonely road, they witness a murder. The detective, because of the circumstances of being where he is for the reason he is there, does not attempt to catch the killer and does not report the crime. He is later assigned the case and soon realizes that an innocent man is about to take the blame, and the only way he can clear him is to arrest the killer and become a witness against him. The story-teller also has a vested interest in the old case. —IMDb
Henry Levin (5 June 1909 – 1 May 1980) began as a stage actor and director but was most notable as an American film director of over fifty feature films. He broke into film in 1943 as a dialogue director for the films Dangerous Blondes and Appointment in Berlin for Columbia Pictures. He then was contracted to Columbia Pictures as a director along with several other “potentials” who began as dialogue directors: Fred Sears, William Castle, Mel Ferrer and Robert Gordon.
At the end of his career, he finally did some television work, directing some episodes of Knots Landing in 1979 and his last work, the television movie Scout’s Honor where he died on the last day of production. Despite having been a stage actor, his only screen acting credit was in an episode of the 1974 television series Planet of the Apes. —Wikipedia
Unapologetic, wonderfully sordid, and callous-hearted, "Night Editor" (1946), despite its generic storyline, is the way all film noir should strive to be, and, of course, the standout is the ever malicious, come-hither Janis Carter.
