I've been informed by the official powers that be that Mya's release of LUST is NOT Polselli's OSCENITA. Rather the film is TORINO CENTRALE DEL VIZIO (TURIN, HEADQUARTERS OF VICE), a 1979 "poliziesco" directed by Bruno Vali (with Polselli the uncredited director according to the IMDB). The film stars frequent Polselli actress, Rita Calderoni.
Trash Online's bootleg of this title describes: "Super-rare, almost lost film by Bruno Vani and co-directed by the late, great Renato Polselli. It is interesting to see how a filmmaker like Polselli does in the crime/police genre. What you can expect is a film full of violence, sleaze, rape, nudity and various sexual situations. Mastered from impossible-to-find materials, this is a fair quality print."
