His maximal studies of US institutions such as welfare bureaucracy and an intensive care unit were packed with human detail and free from explicit commentary
• Frederick Wiseman, prolific documentary film-maker, dies aged 96
The documentary form is often thought to be governed by a manageable feature-length high concept: the story of a person, an institution, an historical episode. The subject itself and the film’s attitude towards it, its editorial slant, are habitually plain enough and the procedure is metonymic: the camera focuses on a part, and the whole is illuminated by implication. Often they have a sexed-up, quirky story to tell, which might mean a selective and sneakily tendentious approach to editing the material. But that is not quite the case with the films of Frederick Wiseman. His colossal, immersive movies about ordinary people and ordinary lives enclosed in some kind of institution, and characterised by the absence of voiceovers, intertitles or the off-camera directorial presence of the interviewing voice, are not amenable to the elevator pitch; they are the entire elevator shaft itself, and the whole building that houses it.
Whereas epic-length films might be generally held to be appropriate for big and distinctively historical subjects, such as Claude Lanzmann’s Shoah or Marcel Ophüls’s The Sorrow and the Pity, Wiseman applies the maximal approach to static cross-section studies of sometimes less obviously momentous topics such as Paris’s Crazy Horse nightclub or the French restaurant Le Bois Sans Feuilles. However his greatest works are top-to-bottom body-politic pictures of public institutions, huge, intricate constructions of unglamour; his movies themselves were virtual institutions, movie-edifices mirroring their subjects in architectural form and indeed almost always funded by one particular public institution: PBS, the Public Broadcasting System.
