Toronto Summit 6.5 min 1988:
Photographed during the convening of G7 leaders in Toronto, Kneller’s materialist documentary pits street activists against the forces of law and order. This inner city portrait shows a metropolis battened down for possible conflict – its streets closed and cordoned off while helicopters circle overhead in perpetual surveillance. As the film proceeds through dialectical montage, the two sides gather, the black shirts from windowed enclaves, and the protesters who gather to sing, dance and make speeches. Finally open conflict breaks out, as the barricades fall and both sides clash in order to lay claim again to streets too easily ceded to global oligarchy.
