“Shoreline Movements” is a film program that approaches the threshold between land and water as a material environment and as a provocative metaphor for the uncertainties and conflicts of worldly existence. By attending to the shifting frontier of the shoreline and the organisms that inhabit it, we can learn to think ecologically, which means understanding the fluid relations that exist between a vast array of agents, to the point that presumed separations between them are put into question. Sometimes these relations are harmonious, but they can equally be characterized by discord and violence; the shoreline is where seemingly irreconcilable worlds confront one another in negotiations without end.
