After spending more than two years following Romeo Castellucci’s work through international tours, rehearsals, archives, and meetings with collaborators and scholars, Giulio Boato created *Theatron*, an immersive work that paints a portrait of one of the most influential and radical figures on the contemporary theater scene. The film traces over twenty-five years of artistic exploration, weaving together fragments of performances, archival material, and firsthand accounts to construct a journey into a unique theatrical imagination. 
More than a simple visual biography, *Theatron* takes the form of an exploration of theater itself: its origins, its function, and its ability to question the present. Through the exploration of seminal works—from the early days of Socìetas Raffaello Sanzio to major international productions, including creations that have since become iconic—an artistic practice emerges that constantly challenges the relationship between image, body, language, and audience. 
Set to the music of Vivaldi, the film alternates between scenes from the performances and reflections by Castellucci and some of his closest collaborators—playwrights, composers, choreographers (including Cindy Van Acker), critics, and actors (including Willem Dafoe) —offering a glimpse into a creative process that is normally invisible and capturing the complexity of a journey that has redefined the language of contemporary theater.
