I have a soft spot for portmanteau horror films, especially those made in the UK during the seventies. They often have an impressive cast of character actors and offer a snapshot of fashion, culture and sensibilities from the times. However, their weakness often lies with the inconsistency of the various stories. These can range from the outstanding, to what can best be described as filler. Furthermore, although the latter category have just as short a running time as the other vignettes, it is always the poor ones that seem to drag and disrupt the flow of the film. Tales That Witness Madness does not suffer too badly from this problem. Out of the four stories that are featured two stand out and two others are just average and not overtly bad. However, irrespective of potential narrative inconsistencies, there are some good ideas and a ghoulish streak running throughout the fill’s ninety minute running time.
