An immensely popular British crime film, Basil Dearden's The Blue Lamp was scripted by ex-policeman T.E.B Clark, the writer who arguably did most to define Ealing Studio's post-war identity. The film marked the first appearance of the character of Jack Warner – later to be immortalized in Dixon Of Dock Green. The story follows two London policemen whose daily routine is interrupted by a botched robbery and subsequent murder hunt. Starring Dirk Bogarde it was originally released in 1950.Extras:New Locations featurette with Richard DacreLondon locations stills galleryProduction Stills galleryBBC Radio 3 The Essay: British Cinema of the 1940s – The Blue Lamp audio featuretteExclusive Audio Commentary featuring Jan Read & academic Charles Barr
