Heatherly Ben Williams as Policeman at Nora's Garage Christopher Lee as Second Constable Production The film was originally known as Double Pursuit. It was produced by Sydney Box who had just taken over as head of production at Gainsborough Studios and was keen to develop new talent via lowered budgeted movies. The film was based on a story by journalist Maurice Wiltshire, his first for the movies; it was the first screenplay for Frank Harvey, first credit as full producer for Anthony Yarnborough, first film for Alfred Roome, first film for the editor and cinematographer, and first starring role for George Cole. Filming started in December 1947. Gainsborough had meant to make another movie that month called Roses Her Pillow, but production on that was postponed when Margaret Lockwood refused to star and Sydney Box could not find anyone he felt was suitable to replace her, so brought forward Double Pursuit on the studio's schedule. The original stars announced were Jack Warner, John McCallum and Peter Hammond. McCallum and Hammond did not appear in the final movie. The film was shot in 45 days, nine ahead of schedule and £20,000 under budget. My Brother's Keeper'''s exterior location sequences were filmed in the Buckinghamshire/Oxfordshire border area, including scenes shot at the now abandoned Aston Rowant railway station. Several people who worked on the film were rewarded with long-term contracts at Gainsborough. ReceptionMy Brother's Keeper is a well-regarded film, with a reputation as a tight, tense and fast-moving thriller with Roome's previous editing experience being well utilised. The characterisation of the two main protagonists is praised for going deeper than the stereotypes of the tough, reckless criminal and the dim, hapless innocent. Via the 1950 film The Blue Lamp, and Dixon of Dock Green, the TV series developed from it
