As the new series of SBS’s film revitalisation project airs, Guardian Australia’s film critic considers the consequences of this trend in film-making

Paolo Cherchi Usai – the Italian curator and former head of the National Film and Sound Archive of Australia (NFSA) – once put forward an elegant definition of moving image preservation, calling it “the science of gradual loss and the art of coming to terms with its consequences”. Those melancholic words present the dispossession of our celluloid and digital pasts as inevitable, and efforts to maintain them a will-o’-the-wisp exercise: impossible to achieve, like reaching the gold at the end of the rainbow.

But loss is far from the first thing that comes to mind after watching the second season of SBS’s four-part documentary series Australia in Colour. Separated into different themes, the first episode is devoted to family, exploring issues such as changing gender roles, the stolen generations and the arrival of contraceptive pills; the second, about sport, investigates national heroes and drinking culture.
