The Blue Lamp is a 1950 British police drama, directed by Basil Dearden and starring Jack Warner as veteran PC Dixon, Jimmy Hanley as newcomer PC Mitchell, and Dirk Bogarde as hardened 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).
