Keen to learn more and expand into the universe, humankind has always been fascinated with unknown creatures. During the last century, aliens in particular have become a pop-cultural phenomenon. However, the depiction of extraterrestrial life, or the otherness, in films as well as other media has changed over the years. One aim of this paper is to show in how far the depiction of otherness has changed, exemplified by Ridley Scott’s Alien (1979) and Christopher Nolan’s Interstellar (2014). By comparing both films, I attempt to provide evidence for the thesis that possible differences in the depiction occur due to socio-political contexts and how this has changed throughout the last decades.
