This article presents an approach to illustrate fundamental theories of ethics through the use of the television series "Game of Thrones." Fundamental theories of ethics are illustrated by the situations and decisions made by the TV series characters. Each episode has the potential to serve as an effective tool for discussing ethical philosophies, such as utilitarianism, pragmatic egoism, and existentialism. The presentation of each ethical stance is evaluated and includes an analysis of the ethical principles of a character from the perspective of deontological, teleological and subjective ethical theories. A pre-test and post-test of forty-three sophomore students studying in a business school was conducted to assess the instructional value of this teaching tool. The findings indicate this approach had a positive effect on developing an understanding of ethics.
