First major theatrical film of actress Olivia Hamnett. Publicity for this film stated that this was Hamnett's first theatrical film but Hamnett had starred in the little-seen low-budget Australian film Plunge Into Darkness as well as appearing uncredited in The Spy with a Cold Nose.
The house seen in the film, owned by a lawyer (Richard Chamberlain), was rented, from a doctor. The house was situated in Adelaide's leafy suburb of Mitcham.
The dark and black, stormy and rainy weather conditions were created by using wind machines and gigantic hoses, the latter being operated from a number of fire engines.
Katrina Sedgwick, who as a child, played one of the little Burton girls, is now the Director of the Adelaide Film Festival. This was Sedgwick's first feature film.
Director Peter Weir states in an interview on the DVD that this film asks the question: '"What if someone with a very pragmatic approach to life experienced a premonition?"'
This Australian film was partially financed by an advance sale to the American major film company United Artists (UA) for rights to all English speaking territories outside of Canada and the USA. UA provided approximately half of this film's estimated $750-810,000 (Australian) production costs which equated to approximately $350,000 (Australian). Interestingly, UA did not actually distribute this film in the USA, World Northal Films Corporation did.
The producers of this film intended for this film to strongly reach the American market. Richard Chamberlain was imported to headline the film, American writer Petru Popescu was brought in to co-write the film and sales and distribution were set-up with American major United Artists.
This film was retitled from 'The Last Wave' to 'Black Rain' for distribution in the USA. The film was made and released about twelve years before the Michael Douglas unrelated film of the same title, Black Rain.
Prior to the casting of Richard Chamberlain in the lead role, two Australian actors were considered. One was rejected and the other wasn't available. A short-list was made of six actors who had international recognition. Chamberlain was sent the script which he thought interesting but was at first cautious about making a film in a foreign country and with a director he was unfamiliar with. Peter Weir visited Chamberlain at the Broadway Theatre where he was starring in 'Night of the Iguana' and the two clicked. Chamberlain was then screened Weir's previous film Picnic at Hanging Rock where the film had yet to be shown at all in the USA. Chamberlain liked this film and at some time soon after this, Chamberlain was signed.
The city of Adelaide doubled for the city of Sydney alot in this movie. During production, Sydney experienced harsh weather conditions with constant heavy rain. Such weather, ironically, had to be recreated in Adelaide, which was sunny and pleasant during filming.
Reportedly, producers Hal McElroy and Jim McElroy mortgaged their homes and their business interests in director Peter Weir's previous film Picnic at Hanging Rock so this picture could maintain its cash flow and continue production.
Of the three main films that then Australian child actor Greg Rowe starred or appeared in for the South Australian Film Corporation, Storm Boy, The Last Wave and Blue Fin, all three films featured storms and bad weather.
