This study examines mythologems, myths and archetypes as a plot-forming factor of adventure genre films on the example of the national Belarusian cinema. Adventure cinema, being the most popular genre group among the viewers all over the world, has always been characterised by a great influence of mythological motifs on its plots. Adventure films are the fulfilment of the viewer's dream of an adventurous experience. For the sake of satisfying this spectator's dream, mythologems are present in them, as they are the accumulated experience of generations of basic fabulae, the embodiment of which the spectator expects to see on the screen. The correspondence of the plots of adventure films to mythologems that have been absorbed by the historical and cultural experience of mankind makes it possible to understand and accept the plots of such films practically outside the temporal and territorial boundaries of national cultures.
