Thirty years ago the five-time Academy Award winner Federico Fellini passed away. In this circumstance I have decided to pay tribute to him, analyzing one of the most underrated movies of the Italian director: Giulietta degli spiriti (Juliet of the spirits). Dismissed by the critics since its release in 1965 as “a lackluster parody of 8 ½” (Goffredo Fofi), this new cinematic immersion in the world of psychoanalysis is above all a project conceived for Fellini's muse Giulietta Masina. However the actress didn't just play a role written in a script; she also went a step further because, deviating from director's intentions, and so bringing them to new semantic horizons.
