The Hundred Hour Hunt (1952)

EMERGENCY CALL is a film that takes an old premise, involving a sick and ailing child who desperately needs to be saved by a transfusion of rare blood, and uses it as a basis for a film which explores working class life in London in the early 1950s. It's an intriguing little portrait of its time, depicting a bygone era populated by racial tension, corrupt boxing promoters, and criminals desperately trying to cover up their past crimes. The film is episodic in nature and hampered by the constraints of a low budget, but not without interest for fans of the genre.

The cast includes Jack Warner (TV's DIXON OF DOCK GREEN) playing, you guessed, a policeman, and real-life boxing champ Freddie Mills playing, well, a boxer. There are also roles for those who would achieve later fame, including Thora Hird and Sid James. The film shrugs off the social commentary about two thirds of the way in, ending up as a police procedural thriller with an effective climax. Not great, but there's still plenty of interest here.
