This paper examines the role of film as a propaganda tool in the context of national narratives in Croatia, Bosnia and Herzegovina and Serbia during and after the war from the beginning of the 90s and after. Through the analysis of the history and contemporary state of the film industry in these countries, it will be investigated how films are used as a means to promote national identities, ideologies and political interests. Films reflect collective experiences, challenges and changes that countries have gone through and have the ability to imperceptibly influence people outside the consciously manageable field, bypassing rational thinking. The analysis of dominant national narratives and ideologies in the mentioned countries reveals different dynamics and characteristics within their film production and distribution. In all these countries, the film industry is not only a means of entertainment, but also an important carrier of cultural heritage and historical awareness. Films are reflections of collective experiences, challenges and changes that countries have gone through. But the most important feature of films, which allows them to be used as a means of propaganda, is their ability to have a covert, unnoticed influence on people. The influence is usually in a sensual form outside the consciously manageable field, which helps to bypass rational thinking.
