I don't feel this film can be divorced from Jane Arden's evolution in to radical feminism and R. D Laing's 'Anti-Psychiatry' movement of the 60's. It is more than a film, it is a jarring polemic. Jane Arden and Jack Bond made 3 of the most unique 'art films' of British cinema: 'Separation', 'The other side of underneath' and 'Anti-Clock' (in which they experimented with and pioneered video techniques). Not a trilogy more a triptych on the sense of self, it's disintegration and the internal and external influences on that process. Where as 'Separation' can be humorous and 'Ant-Clock' dream like. 'The other side of underneath' is a dark night of the soul, the nightmare that lingers when you wake. All beyond narrative description. Caveat Inspectoris (I have never studied Latin please don't be harsh)
