Ah yes Ilsa,Here is one of the Ilsa sequels from 1976 "Ilsa,Haremkeeper of the Oil Sheiks" starring Dyanne Thorne as Ilsa.This film's title is fairly self explanatory
in a half a dozen words .One of the better features of this film is the appearence of Uschi Digard,as in that period of of the late sixties thru the mid 80's she was one of the superstars of big boob adult films.
Dyann Thorne,somewhat along the lines of Betty page,found a spiritual calling as I have seen several references to her living in Las Vegas and working as an ordained minister.Ushi Digard makes her home in Palm Springs these days,but I have not seen any mention of her present occupation.I am still waiting to see a posting that credits one of the adult movie starlets as once retired from the films going out and starting their own rope or leatherworks company!
