The humanity of Mastroianni, the irony, the easy-going self-deprecation, the rejection of his star image, the remaining human, with the weaknesses and fragilities that are part of a man’s soul, are the characteristics that Silvia Scola and Fabrizio CoralLo have examined in order to give us a portrait of the most media-covered Italian star ever, whose charm has never gone out of style, thanks to the choices he made during a Long career in which he had the courage to play roles that few other actors who had achieved his level of fame would accept: a cuckold, an impotent man, a homosexual, a cad, a pregnant man. He accepted, sometimes chased, these roles in order to challenge himself, to free himself from the tight cage of the “Latin Lover” that his charm and the worldwide success of La dolce vita risked imposing on him. MarcelLo, a rare case in which an actor is associated more with his first name than his surname, understood immediately, with a sensitive lucidity, the risks associated with being the first Italian actor exposed to the blinding lights of worldwide media fame. Through an extraordinary work of research in Italian and international archives, this docufilm paints us a rich and entertaining picture of the many nuances of Mastroianni, an artist who, though nearing what would be his 100th birthday, still feels like a contemporary.
