The Scales of Justice is a series of thirteen British cinema featurettes produced from 1962 to 1967 for Anglo-Amalgamated at Merton Park Studios in London. The first nine were made in black and white, and the last four in colour. The finale, Payment in Kind, was Merton Park's final production. Episodes were based on criminal cases, and each film was introduced by criminologist Edgar Lustgarten. The series derives its title from the symbolic scales held by the statue of Justice, situated above the dome of London's Central Criminal Court, The Old Bailey. The opening narration describes her as having "in her right hand, the Sword of Power and Retribution, and in her left – The Scales of Justice".

White Corridors was based on Yeoman Hospital, a novel by Helen Ashton. Told episodically, the story concentrates on the day-to-day activities in a busy hospital, where research pathologist Neil Marriner (James Donald) conducts experiments in the hopes of curing diseases impervious to penicillin. Marriner is aided in this endeavor by lady surgeon Dr. Sophie Dean (Googie Withers), who happens to be in love with him. After a tragedy occurs for which Marriner holds himself responsible, the film builds steadily to an exciting climax involving a untested -- and potentially dangerous -- serum. The top-rank British supporting cast includes Barry Jones, Moira Lister, Petula Clark, Basil Radford, Dagmar (later Dana) Wynter, Bernard Lee, and, in a minor role, future "Dr. Who" Patrick Troughton.
