16 July 2014, 18 year old James enters a phone booth in Shipley, North England, tostart a dialogue with his future self, posing pressing questions about the futureof his life and world. One year later, 19 year old James walks into the same phonebooth responding to his past self, revealing changed outlooks and perspectives. Duringthe year, a shopping centre is being built in the background of the phone booth, puttingthe change of time and immediate environment of James' home, on display. The ethnographicfilm Call Me Back is in postproduction and part of an on-going research project on ‘ethno science fiction’ as a method in Visual Anthropology. The research presentationwill draw on the film project to explore how projective improvisation in ethnographicfilm could contribute to the anthropological understanding of how the participantsof the fieldwork and filmmaking relate to the future, especially with regards to scientificpredictions about environmental and climate change.
