Before starting production of the film, director Claudio Caligari, already severely ill, said to producer and friend Valerio Mastandrea that he felt like he was going to die like a loser, having made only two movies. Mastandrea replied that there were people who made thirty movies and were way bigger losers than him.
The first scene with the ice cream is a self-reference to Claudio Caligari's movie from Toxic Love (1983).
