In Interstellar the manipulation of time occurs in two specific ways: narrative time, or the arrangement of the events in the plot in a certain artistic form, and time warp, which is a scientific term signifying the relativity that occurs along the space-time continuum. While we can certainly find films by Nolan in which narrative time has been arranged much more radically than Interstellar, in none other we might locate time warp. Time warp is to be considered as the agent of the Real because it creates a prolonged trauma, a threat, or, to be more exact, a fear of imminent death. As we witness, the effect of time warp is sometimes boosted by narrative time in certain spots in the film. The beginning of the film, therefore, is its ending: the narrative, in this sense,Here, the surplus is the ending of the film, which appears in the beginning, in the image of Murph as a very old woman. The function of this surplus is to reveal the sad truth about desire.
Not only does John Brand tell a big lie to send people into space travel, but also he supports the ideology of capitalism under the name of human values. He is the father figure and the perfect representative of the law in the film.
