Hello she is not Fides Stagni.
And with this topic we can (sadly resolve the mistery of the unidentified grey haired-old woman) as you remember we say that maybe that woman would be Gina Stag.
Very sadly she is not,because Gina Stag is the woman of this topic.
Infact some time ago i read on the imdb that Gina plays in Vincere per vincere
the role of old woman,i was given this pic from a guy who have the movie,and kindly take this pic for me,when i ask him if he can found in the movie vincere per vincere an old woman.
After this i checked again Luci lontane,and the woman at the cimiterium in this topic is present in the movie Luci Lontane with a wig (she is with one of the protagonist which is in the bed),so sadly Gina Stag is the woman in this topic and not our beloved generica.
