Oh, yes, of course! I didn't recognize her in the nun-habit. Very nicely spotted, Emiliano!
She actually has a rather important role in this film - she appears in many scenes and has plenty of dialogue. She should be credited! And there is an unidentified actress named Ornella Picozzi in the credits so it could
actually be her, even though the other films in Picozzi's filmography are porno films...
I don't know but here are at least a few more pics of her from La vera storia
