Director Ossorio liked employing the same actors
You've got to hand it to Director Amando De Ossorio for loyalty. He would rehire the same actors and actresses in his Euro-horror flicks, starting with the 'Blind Dead' series, to other horror flicks like, "The Loreley's Grasp". In all fairness, there seemed to be a defined group of Euro actors and actresses who seemed to specialize in early 70s Euro-horror flicks. We'd see these same actors and actresses in other contemporary European (non-British) horro films, for example, the Paul Naschy horror films, one example being, "Horror Rises From the Tomb". You just have to get used to seeing the same actors and actresses get torn to pieces in one horror flick and show up in another and another. I guess there was no such thing as being type-cast back in those days.
SILVIA TORTOSA is one of my favorite, beautiful Euro-horror actresses from the early 70s. I first saw her in the 1973 Euro-horror flick, "Horror Express", starring of all people, Telly Savalas, Peter Cushing, and Christopher Lee. Silvia had a saucy sexy face that sometimes carried an arrogant, stuck-up b-tch look to one of innocent terror. Usually stuck-up girl looks turn me off, but in Silvia's case, only made me like her more.
The intrepid hunter, Tony Kendall, was also employed by director Ossorio in, "Return of the Blind Dead".
