[3] Fragasso would later go on to write and direct his own films in the 1980s, including Monster Dog with rock musician Alice Cooper and After Death.
[9] In 1980, Mattei began a close collaboration with screenwriter Fragasso, beginning with The True Story of the Nun of Monza (1980) and ending with a comedy called Three For One (1990).
[2] The two worked closely together for that ten-year period (collaborating on 15 films)[2] with Fragasso occasionally assuming the role of second unit, or assistant, director.
[10] Fragasso spoke positively on working with Gemser, stating that "compared to the starlets of today, she was virtually a nun, the absolute opposite of a porn star".
[10] Gemser would years later work for producer Aristide Massaccesi's Filmirage team, as a costume designer on Fragasso's film Troll 2.
[10] Producer Roberto Di Girolamo requested a post-apocalyptic film from Fragasso and Mattei, called Rats: Night of Terror.
[4] In 1986,[1] Fragasso made a film on his own without Mattei titled Monster Dog for producer Eduard Sarlui, starring musician Alice Cooper.
[14] Fragasso has claimed that he and Drudi wrote the original story for Filmirage's Killing Birds which they wrote under the title Artigli, a claim dismissed by Italian film critic and historian Roberto Curti, who noted that the treatment for Killing Birds, that was written by Claudio Lattanzi and Bruna Antonucci, was much closer to the finished film.
[17] This new wave included Fragasso's Palermo - Milan One Way, the box office success of which led to others such as Coppia omicida and the television film Operazione Odissea.
