Borders are omnipresent in today’s debates about belonging, identity, migration and security. The nature of territorial borders transforms constantly as a result of globalization, neoliberalism and different kinds of bordering practices. Cultural artefacts – such as films – can provide a rich insight into how borders are constructed, experienced and challenged, but there is little systematic or large-scale research addressing the cultural dimensions of borders. More knowledge about these dimensions can help us to better understand the malleable character of borders, their historical contingencies and their various subjective meanings for different societal groups. The overall objectives of REEL BORDERS are to (1) map how film has been used to construct particular borders, by conducting film analyses; (2) analyse through interviews and content analyses why and how different actors, organizations and institutions use film to tell particular stories about borders; (3) understand border experiences of borderlanders through visual methods such as participatory filmmaking and cineforums. Ultimately REEL BORDERS seeks to develop a new theory on border imaginations that includes film as well as multiple subjective perspectives. The project’s participatory films will also enable public circulation and awareness regarding social issues in Europe’s border regions. REEL BORDERS focuses on three border regions around the borders of UK-Ireland, Spain-Morocco and Turkey-Syria.
