Io so che tu sai che io so

The film has some imperfections, such as the fact that only an absolutely idiotic private detective can follow someone only by the license plate of a car, the first important thing being the person's identity, name, surname and, absolutely mandatory, a photo of the person being followed. Then, all we see in the films filmed by the private detective, which Fabio (Alberto Sordi) watches in the country house, are scenes that are too intimate down to the smallest detail, in terms of image and sound, which would could be almost impossible for a private detective to obtain. Overcoming these flaws, the film is captivating. Certainly, everything is due to Monica Vitti and Alberto Sordi, the greatest comedic and dramatic actors of all time. If there were two other actors, the film would not be as good.
