Monolith (1987)

John Hurt narrates this highly charged and doom-laden public information film from the 1987 AIDS awareness campaign. A cliff-face explodes in slow motion; an industrial drill bores into a huge block of rock; the word 'AIDS' is chiselled into the polished surface of a granite headstone and a "Don't Die of Ignorance" leaflet drops onto the surface along with an elegiac bouquet of white lilies. The solemnity of the accompanying voice-over quells any vestiges of ambiguity.
