As Carlson notes, “even within the already established challenges of Manoel de Oliveira’s body of work, Inquietude stands out for its unique difficulty. For the sake of convenience and an initial direct access, it’s easy enough to allot a general theme to most of the other films (e.g. Vale Abraão is about beauty, O Convento is about evil, La Lettre is about love, etc.). This at least allows for some means of approach, but Inquietude defies any such orderly schematic. What is it about finally? One is tempted to say death or immortality or notions of the eternal but somehow even these broad terms do not seem adequate enough.
Finally, it really must be that titular disquiet, an existential unease or angst. But this is even more vague than usual, given that it describes a foundational condition upon which everything else is built or develops. It’s a self-awareness that gives rise to poetry, philosophy, the specific conditions of human cognition itself (the comprehension of immortality as an idealized quality, for example). The synthesis brought about by this shifting set of contexts and active agents produces a surfeit of meaning. One character demonstrates the effect of that supercharge of ambiguity in noting on a friend’s lover: ‘She is dead. In your mind, she is not the same.’
Narratively and structurally the film is a triptych. The three stories it contains are laid out in an interwoven, interdependent form. The first is a rather confined, even claustrophobic, extended dialogue between an aged, successful scientist father and his almost equally acclaimed middle aged son. The discussion centers around insuring a lasting legacy (i.e. immortality) and the means by which to secure it (i.e. suicide at the peak of one’s renown). This broad comedy verges often on farce and, once it pitches irretrievably over the edge, is revealed as a theater performance witnessed by characters from the second story, one set within the upper tier environment of Portuguese society in what would appear to be the early part of the twentieth century.
In this section, the unnamed male lead is troubled by his love for a courtesan, Suzy. Eventually he is comforted by a friend who tells him a mythic folk tale which in turn is also told to us cinematically. In it, a dissatisfied young peasant girl in an isolated rural area assumes the identity of Mother of the River from another woman, virtually immortal, who has grown dissatisfied herself with the role. The transitions between these stories could not be more readily apparent and clearly administered. What the implication of their association is cannot be so easily assessed. As is remarked by the friend in the second story: ‘There’s a connection and yet none at all.’”
