This article discusses the motif of time travel in the science-fiction film Interstellar (Christopher Nolan, US/UK 2014). Time travel is a common motif in modern science-fiction films and series. The discussion here focuses on the anthropological dimensions of time travel from a hermeneutic perspective. Interstellar contains both a climate catastrophe and a technological optimism that enables time travel. The pseudo-scientific time travel is connected with symbols from the Christian tradition. Intriguingly, time travel is portrayed in light of indirect physical communication. From an anthropological perspective, pseudo-scientific time travel reflects and explores identity issues. The crossing of space and time and their simultaneous constraint lead the viewer to reflect on their own cultural life-world. In Interstellar, time travel is a journey into the past that locates the traveler back in the present and brings hope for a better future.
