The title is presented in reference guides as TRA(SGRE)DIRE and in the film itself with the middle four letters smaller than the rest of the title. The verb "Trasgredire" translates from Italian as "to transgress" while the verb "Tradire" (minus the "sgre") translates as "to betray."
Tinto Brass met Yuliya Mayarchuk while she was a waitress in a pizzeria and invited her to audition for Dream (1999). Mayarchuk remembers that on the day of the audition, along with her, there were many other applicants, including some prostitutes. Finding herself alone with the director, he asked her to undress. "He asked me to show him my boobs and asked me if they were fake," says the actress, who then also had to take off her clothes from the waist down. "He complimented me because, he said, I have a nice butt," the actress adds. Finally Mayarchuk was chosen by Brass also to play 'Carla' in this movie.
Yuliya Mayarchuk revealed that the two most difficult scenes for her were the one in which she has sex in a gondola (she had to put a fake penis inside her vagina and she started crying) and the infamous anal sex scene on a beach with Mauro Lorenz. "I didn't sleep the whole night before," Mayarchuk recalled. "I had straight hair. Shoot a scene like that! I had some kind of psychological block. An anguish inside, until the take. It was too private a situation, even if it was a fiction. Then I calmed down and everything went well."
