The proposed book uses the Star Trek television/movie and Star Wars movie series to explain key international relations (IR) concepts and theories. It begins with an overview of the importance of science fiction in literature and film/television. It then presents the development of the Star Trek and Star Wars franchises, and discusses how their progression through time has illustrated key IR theories and concepts. As a bonus, it compares the two franchises to another recent science fiction franchise used to teach IR (Battlestar Galactica).
