Mario Alberto Ettore Monicelli was an Italian film director and screenwriter, one of the masters of the commedia all'italiana. He was nominated six times for an Oscar, and received the Golden Lion for his career.

Commedia all'italiana, or Italian-style comedy, is an Italian film genre born in Italy in the 1950s and developed in the 1960s and 1970s. It is widely considered to have started with Mario Monicelli's Big Deal on Madonna Street in 1958, and derives its name from the title of Pietro Germi's Divorce Italian Style (1961). According to most of the critics, La Terrazza (1980) by Ettore Scola is the last work considered part of the commedia all'italiana.
