It is a spin-off from Man About the House, and starred Brian Murphy and Yootha Joyce as constantly-sparring married couple George and Mildred Roper.
Their arrival horrifies their snobbish neighbour Jeffrey Fourmile, a middle-class estate agent who fears the Ropers' presence will devalue his home.
The movie was dedicated to actress Yootha Joyce who died suddenly in August 1980, just as the cast were about to film a sixth and final series.
George and Mildred Roper have left their old house after receiving a compulsory purchase order from the council, and move to 46 Peacock Crescent in upmarket Hampton Wick.
George and Mildred's next-door neighbours are Jeffrey Fourmile, a snobbish estate agent and his wife Ann.
Ann and Mildred become good friends, but Jeffrey is frequently irritated by George, with their spats providing much of the show's humour.
During 1977, Brian Murphy and Yootha Joyce, joined at one point by Reginald Marsh, toured in a successful stage version of the programme.
In 1976 and 1977, Murphy and Joyce appeared as the ugly sisters, Georgina and Mildred, in the London Palladium pantomime, Cinderella.
It would prove to be the former as Yootha Joyce died from portal cirrhosis of the liver due to chronic alcoholism on 24 August 1980, before the film was released.
Friends and colleagues were unaware that Joyce had been habitually consuming half a bottle of brandy every day for over 10 years.
Murphy also revealed that this was due to have been the final series of George and Mildred, as he and Yootha Joyce were afraid of being typecast after playing the characters since 1973 on television and in two films.
However, this project did not materialise, with Brian Murphy briefly moving to the BBC the following year for L for Lester which was cancelled after just one series.
He did reunite with George and Mildred co-star Roy Kinnear and writers Johnnie Mortimer and Brian Cooke for The Incredible Mr. Tanner, a comedy produced by Thames Television.
