Take a look at the review Justine Smith wrote for By the Time We Got to Expo in The Globe and Mail:
“Using Expo 67 as a backdrop, the experimental By the Time We Got to Expo (directed by Eva Kolcze and Philip Hoffman) uses 8mm footage to expose the decay of physical materials and, as a result, the decay of Montreal itself. The concrete modernist architecture built during this era is rendered cracked and apocalyptic under the scratches of the damaged film.”
