Marino Masé (1939 – 2022) was an Italian actor. He appeared in more than 70 films between 1961 and 2006 and is known for performances in such films as Nightmare Castle (1965), Tenebrae (1982) and The Belly of an Architect (1987).
Above is the full version of Nightmare Castle (1965) a mad doctor and the new flesh type of plot film starring a whipped Barbara Steele.
Liebeskonzil (1982) is a film by Werner Schroeter, based on the scandal play The Love Council (1894) by Oskar Panizza.
The play [and the film] are set in 1495, during the first historically documented outbreak of syphilis.
It portrays the dreaded venereal disease as God’s vengeance on his sexually hyperactive human creatures, especially those surrounding Pope Alexander VI.
Panizza was charged with 93 counts of blasphemy and served his full 12-month sentence in prison.
Years ago, I posted [1] two highlights of see-through erotica.
Both were film stills. The first[3] was from Succubus (1968) directed Jess Franco, the second[4] was from Castle of Blood (1964), directed Antonio Margheriti.
Today, the full movies of these stills are available on YouTube:
From Castle of Blood I was able to find the exact location of the film still in question[4]. The woman who is wearing the translucent crinoline and who bares her perky breasts appears to be Sylvia Sorrente (Elsi in the film).
From Succubus I was unable to track the still. However, I was able to get a wider shot[6]. La Reynaud appears to be stripping for a pianist seen from the rear in the back.
