Nanni Moretti recalls in his diary three slice of life stories characterized by a sharply ironic look: in the first one he wanders through a deserted Rome, in the second he visits a reclusive friend on an island, and in the last he has to grapple with an unknown illness.
Unfortunately the movie Caro diario is not yet available on HBO Max.
