The films were directed by Ralph Thomas and produced by Betty Box. The films inspired several spin-off television series.
The first film, Doctor in the House, was initiated by Betty Box, who picked up a copy of the book at Crewe during a long rail journey. She saw its possibility as a film, but Box and Ralph Thomas had a job convincing Rank executives that people would go to a film about doctors, and that Bogarde, who up to then had played spivs and World War Two heroes, had sex appeal and could play light comedy. They got a low budget, and were only allowed to use available Rank contract artists.
