Actor/director Carlo Verdone recalled in an interview that his mentor/producer Sergio Leone hated the character of Furio, whose scene were ultimately saved because Alberto Sordi and Monica Vitti, invited to an early private screening of the movie, found him amusing.
The three characters drive cars each one in one of the colors of the Italian flag: a green 1963 Fiat 1100 D (Mimmo), a white 1978 Fiat 131 Mirafiori Panorama (Furio) and a red 1973 Alfa Romeo Alfasud (Pasquale).
Producer Sergio Leone was initially against the title "Bianco, Rosso e Verdone", as too similar to Bianco rosso e... (1972), which had been a box office flop.
For the character of Pasquale Amitrano, Carlo Verdone was inspired by French mute actor Jacques Tati, of which he is a fan. Verdone wanted to compensate the talkativeness of character Furio Zoccaro with an almost mute character.
Carlo Verdone was initially not much convinced with making this movie, fearing a flop, and decided to go ahead only after a long period of reflection in his country home.
