Io so che tu sai che io so

It is surprising to me how little is this movie known, even in Italy. I watched it when I was a child and then again as an adult, and I always found it simple and impressive.

Sure, the idea that the private inspector might follow the wrong person is silly, but the personal path of the couple played by Alberto Sordi and Monica Vitti is realistic and convincing.

Many of the movies made by Alberto Sordi had simple messages, and this one as well, something that based on popular wisdom, not on intellectual sophistication, and I think that this coherence with his believes gives the movie its strength.
