Nesse paradigma, Capitão América: Guerra Civil é lançado com uma simbologia contestadora do papel do hegemon no sistema internacional. Com isso, inicialmente é exposto o enredo do filme, seguido das teorias liberal e realista das Relações Internacionais e da semiótica greimasiana. Com isso em vista, é feita a análise dos símbolos do longa-metragem e, por fim, se conclui que os autores do texto tinham como objetivo disseminar uma mensagem de união política entre os americanos.     Abstract: Observing the unipolar system emerging from the closure of the Cold War, is remarkable the sentiment of geopolitical insecurity generated by the existence of only one global superpower and the doubts about the role of the sovereign State in such system.
