Nijiotoko

A newspaperwoman tries to prove her friend didn't kill her uncle at his home and cover it up by setting the place on fire. As the police investigate, they discover a family obsessed by rainbows, and the threat of a 'rainbow man' who makes weird things happen.

It's director Kiyohiko Ushihara's first movie after a 12-year layoff during the Second World War, and his last fiction film - he directed a documentary that was released in 1958. This one combines Old Dark House tropes, as well as the sort of scientific bafflegab that would become a standard of science fiction movies, as well as drug use. I found this film to be interesting in its handling and inventive in its camerawork, but there's something off about its pacing that I can't be sure is intended to complement its themes.
