The “Radicalism Trilogy” is a loose thematic grouping of films by Yoshishige Yoshida, consisting of Eros + Massacre (1969), Heroic Purgatory (1970), and Coup d’Etat (1973). While not connected through a continuous narrative, these films are linked as a trio in Yoshida’s exploration of radical politics, historical upheaval, and avant-garde formal experimentation within the context of Japan’s New Wave cinema.
