In 2012 when co-producer Michael A. Martinez met with Michael Forest in a Hollywood coffee shop to hand him an edit of the film, actress Barbara Bouchet (who is mentioned in much detail in the film) walked in and introduced herself, purely coincidentally. Bouchet and Forest casually knew each other as guest stars on episodes of "Star Trek" in addition to their work in Italian films.
The reason for Ottaviano Dell'Acqua having the hairstyle that he does is that his interview was done while he had just finished as Tom Hanks's stunt double in Angels & Demons (2009). His interview was done in the hotel courtyard outside the 2009 Chiller Theater convention in Parsippany, NJ while they were having a retrospective on Italian horror movies. A fellow convention guest and alumnus of Italian horror films, Silvia Collatina was kind enough to act as translator and interpreter during his interview.
