An Average Little Man (1977)
An Average Little Man (, literally meaning a petty petty bourgeois, also known in English as A Very Little Man) is a 1977 Italian drama film directed by Mario Monicelli. It is based on the novel of the same name written by Vincenzo Cerami. The first hour is a fine example of commedia all'italiana but the second part is a psychological drama and a tragedy. The film was an entrant in the 1977 Cannes Film Festival.
