Orson Welles' voice was dubbed into Italian by another actor.

The section entitled "La Ricotta" is featured on the 2-Disc Criterion Collection DVD for Mamma Roma (1962).

Orson Welles, who portrays the director of a Biblical epic in this film's 'La Ricotta' story, coincidentally had directed himself in his own scenes in the Biblical epic, David e Golia (1960). Welles, who portrays a king in the film, also narrates another Biblical epic, King of Kings (1961). Welles narrates a portion of the Biblical work The New Media Bible: Book of Genesis (1979) as well. Also, is an uncredited writer on The Bible in the Beginning... (1966).

The title came from the names of the four directors involved - Rossellini, Godard, Pasolini and Gregoretti.

Rossana Di Rocco's debut.
