Book excerpt: Persona is a brooding study of personal disintegration, as Elizabeth, an actress recovering from a severe emotional breakdown, is cared for by Alma, her apparently well-balanced and extrovert nurse. Slowly the barriers that separate and define the two women crumble, and their relationship turns into a bewildering reversal and substitution of their respective identities. Shame pitches Jan and Eva, husband and wife and both professional musicians, into a world torn apart by civil war. Completely brutalised by the progressive breakdown of all civilised standards of behaviour, Jan and Eva's fate reflects how superficial culture, good order and morality are when set against the unconcern of an arbitrary and amoral universe.
