I wonder if this is another undiscovered film with Mary Millington
It is with a list of George Harrison-Marks loops.
I wonder if it is related to 'Intimate Games'
I doubt the brunette is Suzy Mandel, might be Heather Deeley, or even Jenny West Brook or neither of them.

Yep, thats MM, there are probably a few ?lost? Millington films still out there.

It wont have anything to do with Intimate Games though as that was a feature film, and with the exception of Suzy?s brief, non sex appearance in Health Farm, none of those actresses you mention did 8mm films.

Sadly its not one of the early 70s Harrison Marks soft core films listed/available from the ?Green Door? section of his official website.
