Concetto Franco Diogene was an Italian actor.
At a young age he received a contract in the "Sala Carignano" and from 1972 with the "Teatro Duse".
He played primarily in comedies in which he was cast in roles that were amusing due to his body size. The lifelong and spiritually and philosophically interested actor also took on television roles in the last decade of his life.
Diogene was married to Mariella Denari, with whom he lived in Newport Beach, USA. He died at the age of 57 from the consequences of a heart attack.
