Asked if she was uncomfortable during her several nude scenes, Michela Cescon said, "It is a definite choice I made. Two years ago I would never have been able to, but precisely because I am more adult and aware today it doesn't weigh me down. After I tried my hand at Pasolini's texts in a theater-body/word I really liberated myself. And now I like to shake the banal idea we have of the body-showcase by highlighting instead the real body, the one that bears the signs, of anything, even of old age. Matteo's film opened up this avenue even more, I had to act as I was, without even a thread of makeup. It was a very strong transition for me as an actress."
Michela Cescon, who plays Sonia, actually lost 15 kilograms (over 30 pounds) in weight during the making of the film, as the role required.
The film is inspired by the novel "The hunter of anorexics", an autobiography written by Marco Mariolini, an antique dealer from Brescia (Italy) who was obsessed with very skinny women. Mariolini was sentenced to 30 years of jail after killing a young women with 22 stabs.
