The first short films from the Allegro Polish Legends series attracted great popularity. Further productions were created on the wave of this trend – short films, audiobooks and music videos. A feature film was also announced. The Legends are a unique narrative in Polish popular culture, not only because of the circumstances of its creation, but also the manner of its execution, distribution and the subject matter. In the article, I analyse this popular series, judging whether it can be considered a transmedia narrative. Firstly, I reflect on concepts such as an entertainment supersystem, a universe, a narrative and a transmedia story. Secondly, I relate these concepts to The Legends in an attempt to ascertain their applicability in an analysis of the series. I also reflect on the current situation of the franchise, as well as its potential and development prospects.
