The Blue Lamp is a 1950 British police procedural film directed by Basil Dearden and starring Jack Warner as PC Dixon, Jimmy Hanley as newcomer PC Mitchell, and Dirk Bogarde as criminal Tom Riley. The title refers to the blue lamps that traditionally hung outside British police stations (and often still do). The film became the inspiration for the 1955–1976 TV series Dixon of Dock Green, where Jack Warner continued to play PC Dixon until he was 80 years old (even though Dixon's murder is the central plot of the original film).

Plot

The action mostly takes place in the Paddington area of London and is set in July 1949, a few years after the end of the Second World War. PC George Dixon, a long-serving traditional "copper" who is due to retire shortly, supervises a new recruit, Andy Mitchell, introducing him to the night beat.
