“The Rainbow Man” sounds like quite a cheerful fellow, doesn’t he? How could you not be excited about a visit from such a bright and colourful chap especially as he generally turns up after the rain has ended? Daiei have once again found something happy and made it sinister in this 1949 genre effort which is sometimes called Japan’s first science fiction film though there isn’t really any sci-fi content here so much as a strange murder mystery with a weird drug at its centre.
The story begins with lady reporter Mimi beating her rival Akashi to an important scoop but soon after she runs into an old school friend who seems about to become a major story herself. Yurie has been taken in for questioning regarding a mysterious incident in which a rural cottage burnt down with the body of a murdered man hidden inside it. Heading into town with her maid, Yurie was taken ill near the crime scene and the maid left to go get help meaning Yurie can’t account for the hour or so that she was alone there and being so ill her memories aren’t clear either.
The case at hand concerns the extremely strange Maya family which is led by the mad scientist father who insists on studying artificial rainbows despite an ancient curse on his family which makes this a very bad idea. He is joined by his equally mad artist son Katsuto who creates disturbing, psychedelic paintings, younger son Toyohiko who has recently returned after a five year absence, and his second wife who likes Yurie and cats but not much else. The murdered man, Hachiro, was also connected to the family and was the first to fall victim to the curse of the Rainbow Man!
Unlike some of Daiei’s other genre pictures from this period, Rainbow Man (虹男, Niji Otoko) is a little more straightforward and doesn’t feature any particularly complex special effects. That said, the most notable feature of the film is the rainbow effect itself – right before the murders occur, the victims start shouting about the Rainbow Man whilst hallucinating bright rainbow-like colours. At this point, the screen erupts with psychedelic colours in strong contrast to the regular black and white footage of the rest of the movie. As surprising as this effect is now, it must have been truly shocking to the audience of 1949 who were understandably much less used to colour movies let alone the use of colour in films otherwise monochrome.
Though The Rainbow Man is tagged as sci-fi or horror, it’s really much more of a regular murder mystery with a scientific bent. In the end, it all comes down to the effects of the perfectly natural real world drug mescaline which though unusual is not a scientific fiction. The only instance of strangeness is in the bizarre rainbow man curse in which the Maya family is not supposed to be asking questions about rainbows, which is fairly odd thing to be cursed with, but then they are a very odd family in all aspects. There is, however, a strong mad scientist vibe which, mixed with the creepy old Western style house and persistent stormy weather, makes for an excitingly gothic atmosphere.
The special effects were once again designed by Eiji Tsuburaya and, even if this isn’t such a FX heavy film as some of Daiei’s other movies from the period, are always quite exciting. Director Kiyohiko Ushihara does a nice job of keeping the tension up and provides several interesting set pieces filled with unusual compositions which also make good use of gothic lighting.
The Rainbow Man is also quite interesting as an example of female led genre cinema as lady journalist Mimi takes the central investigator spot and is presented as a talented reporter who always seems to outsmart her male counterpart from a rival newspaper, Akashi. The police too, who are also depicted as competent and open minded, take Mimi seriously by valuing her investigative skills and her desire to protect her presumably innocent friend from harm. The Rainbow Man might not be the sci-fi/horror film it is often supposed to be, but it does provide an intriguing murder mystery with gothic overtones and light layer of genre inflected strangeness.
Can’t find any clips of the movie but here’s a recording of the main theme plus some stills:
