Science fiction is a major genre of cinema, capable of bringing imaginary environments with varied aesthetics to life. Driven by the desire to combine one of the disciplines I am studying here in Camondo with the scenographic work of building these kinds of sets, I decided to explore the possible interactions between furniture design and the decoration of imaginary worlds. In order to understand the secret methods used to create these sets, this dissertation includes an interview with an assistant decorator who reveals the tricks of the trade. I then present an analysis of fourteen science fiction films from different eras in order to understand the effects sought through these interactions.
