Julia Saly, born Julia Salinerno, appears in, I believe, fourteen Paul Naschy films, including Night of the Werewolf, Death of a Hoodlum (Muerte de un Quinqui), Inquisition, Operation Mantis, and Panic Beats (Latidos de Pánico). Ms Saly reminds me of why I do the Nerd Girl of Note feature. While there is no dearth of information about Naschy on the web, there are very few bits about Saly, who was in more of his films, according to my research, than any other actress.
Julia Saly appeared in seventeen films, and produced seven films, according to her IMDb entry. We don't have a birth or death date for her there, and there is no Wikipedia entry for her. Obviously Naschy had some reason for using her in his films, but what was it? Were they married, lovers, or just colleagues who worked well together?
While we might not like to admit it, in exploitation and horror films, sex sells. There are plenty of instances where male directors have their famous females; Russ Meyer had Haji and Uschi Digard, Jess Franco had Soledad Miranda and Lina Romay, Jack Hill had Pam Grier, Jim Wynorski had Julie Strain. These actresses, while not always great in their art, were what drew fans in to films and gave inspiration to their auteur counterparts.
