Like Joseph McGrath's previous film, The Bliss of Mrs. Blossom (1968), this comedy had a hard time getting released in its own country. Its American opening had been well over six months in advance of its British one, and the film had been completed over a year before that, as is indicated by the presence of Duncan Macrae, who had died in March of 1967.
In the movie, Louise(Suzy Kendall) tells Rupert(Dudley Moore) that her hometown is Belper in Derbyshire. This is indeed Suzy Kendall's actual hometown.
