Input: Question: How many centuries had the region where Turner took a train journey in 1987-88 been part of USSR where the journey originated? Passage:Perhaps the reason for the appeal of Turner’s work outside the art world is that it pushes the boundaries of both film and politics. Perestroika has been noted by academics and critical thinkers for both its artistic form and commentary on environmental and social issues, most notably featuring in the essay volumes Performing Authorship: Self inscription and corporeality in the cinema and Screening Nature: Cinema Beyond the Human. For Cecilia Sayad, the film’s importance lies in its structures: its function in highlighting the act of authorship as performance, and how the film’s structural devices serve to emphasise the fictionality of narration, how the retelling, even of truth or fact, always and necessarily involves an element of creation and thus fiction. Sayad comments that whilst Perestroika ostensibly interweaves footage of a 2007–08 reconstruction of a train journey across Siberia that Turner took in 1987–88 with that from the original journey in what was then the USSR, it is as much about the workings of memory and filmmaking itself. But Sophie Mayer has commented on how the work uses the idea of pollution as a function of retention, and weaves it through both the social/cultural and natural worlds. Mayer goes further in exploring the contextual importance of the work, comparing Perestroika with works of the filmmakers Lucrecia Martel and Apichatpong Weerasethakul, commenting that each offers a ‘utopian possibility of a post-capitalist, post-industrial, postcolonial moment’. In a booklet of essays written to accompany the publication of Perestroika and perestroika:reconstructed in 2014, another academic, Paul Newland writes ‘the artist explores the nature of representation and its problematical relationship to our experience of reality. By doing this the film travels the branch lines between cinematography, photography, and everyday life.’
