 In the theatrical release version, when she is talking about her husbands  views on sex she says "But it doesnt go as well as the Ford Cortina",  however in the version that was premiered on the BBC this line was dubbed to  "but it doesnt go as well as the Ford Escort". Presumably this had something  to do with product placement in that at the time the film was shown the Ford  Escort was still being made whereas the Cortina ceased production in about  1983.
