Some were quick to compare Seance to The Sixth Sense (1999), both being films that feature mediums who can see the dead. In fact though Seance is really a remake of the British thriller Seance on a Wet Afternoon (1964). Seance on a Wet Afternoon featured Richard Attenborough as a weak-willed husband who catered to his wife, a mentally unstable medium (Kim Stanley), by arranging the kidnap of a child where she would then gain public attention from by pretending to locate with her abilities. Seance on a Wet Afternoon was a classic of psychological tension, as much for the way that everything in the plan started to go wrong, as it was for the bared open characterizations of the two kidnapers.

In his version Kiyoshi Kurosawa substantially changes many parts of the plot. For one he has the medium’s powers as being actual, whereas Seance on a Wet Afternoon assiduously avoided any hint of the supernatural and left one with the impression that Kim Stanley was probably deluded as to her powers. The characterizations have changed notably. In Seance on a Wet Afternoon, the weak-willed Richard Attenborough went into the scheme to help the mentally unstable Kim Stanley, but began to have moral doubts about what he was doing. As in Cure, Kiyoshi Kurosawa is fascinated with the sense of dark buried tensions within marriage and here the wife is the one who advocates the scheme, but now it is because she is sick of a dull marriage and wants something more out of life. (As the wife, Jun Fubuki gives a particularly good performance of fragility and vulnerability). Also here the couple seem a lot more innocent and blameless than they were in Seance on a Wet Afternoon – here they don’t even kidnap the girl, rather they merely take advantage of a situation where the girl, fleeing her kidnaper, hides in an equipment crate and is somewhat improbably carried home unnoticed by the husband. Despite the fact that they do end killing the girl (something that never happened in Seance on a Wet Afternoon), the couple here still seem much less blameless and evil than the other couple – the killing here is merely an accident, contrast that to Kim Stanley in the original urging Richard Attenborough to kill the girl because she has seen his face.

The most noticeable difference between Seance on a Wet Afternoon and Seance is that one is a psychological thriller, the other is a horror film. The first and the final quarters of this film add completely original material over the book and other film that deal with the wife’s supernatural visions. Here Kiyoshi Kurosawa creates an amazingly haunted atmosphere. There’s a really spooky scene where the wife sees a girl in red sitting beside a businessman at a table in the restaurant where she works as a waitress and then moments later the girl casually walks past and we see that she has no legs. Good too are some of the hauntings at the end – the opening of the crate and the emergence of the shadow girl come to slap bloody hands on the husband’s chest; the appearance of the girl’s arm seemingly unattached to anything else coming around the wife’s neck in a restaurant.

Although again, characteristic of Kiyoshi Kurosawa’s films, there are plot elements left unexplained – the appearance of the girl in the red dress is not connected to anything else in the film and is simply forgotten. Why does the husband suddenly develop mediumistic abilities after the girl’s death and he become the one able to see the girl’s ghost rather than the wife? Who is the man he suddenly sets on fire and why?
