A life filled with sweetness. His sweet look, his foxy smile and his legendary indolence allowed him to remain slightly detached and to protect his private life. Even today, saying Mastroianni or Marcello evokes an era: a world made up of skill, beauty, charm, kindness and seduction. The documentary starts off with an old documentary created by Antonello Branca in 1964, in which Mastroianni is shown at the height of his success, and contains interviews with Mastroianni recorded at various moments throughout his life, excerpts from his films, shots taken on set, testimonies from his daughters Barbara and Chiara as well as actors, directors and the people close to him.
