Last of the Summer Wine [SEP] Films
In 1983, Bill Owen suggested to a newly returned producer Alan J. W. Bell that Roy Clarke's novelisation of the show should be made into a feature-length special. Other British sitcoms such as "Steptoe and Son" and "Dad's Army" had previously produced films made for the cinema, but the BBC were initially sceptical as they had never before commissioned a film based on a comedy programme for original broadcast on television. They nevertheless commissioned a ninety-minute film named "Getting Sam Home", which was broadcast on 27 December 1983, and started a trend which would continue with other British sitcoms, including "Only Fools and Horses".
