This romantic spy movie, which is partially set in Barbados, was first released in the same year as the James Bond film The Man with the Golden Gun (1974).

Screenwriter Earl Hamner Jr. was originally attached to pen the screenplay according to the 24th December 1971 edition of show-business trade paper 'The Hollywood Reporter'.

The hiring of Edwards was announced in the 21st March 1973 edition of show-business trade paper 'Variety'.
