The current article discusses the issue that the hero in Sartre's existentialist attitude lives alone and confused in an absurd world where moral foundations are not very important. He is forced to choose and by choosing values, he creates his desired ethics and by this means he invites others to those self-created values. In this way, Sartre gives a new meaning to the word hero. Sartre's hero becomes even more limited by the "other" with his terrifying decisions, the only way to save him is conscious self-deception. Although he knows that he is free and has to choose, and he is also familiar with the responsibility and commitment. The current research was carried out with a fundamental purpose and its main issue is to investigate the characteristics of the hero in Sartre's existentialism philosophy and the conditions of its emergence. In this research, in search of the conditions for the emergence of the hero from Sartre's point of view, it shows that originality is the result of practical actions in the situations in which Sartre's hero is placed, so it is connected with consciousness and freedom is the relationship of consciousness with the world. The research method is qualitative and in order to reveal the research problem, the Paris-Texas film has been selected and analyzed as a case of study based on the purposeful selection. The result indicates that every action of today's hero is original and self-determining because it was formed in freedom. He is nothing but what he makes of himself; This construction happens in the public sphere, so authenticity is no longer an individual action, but a conflict in social relations.
