I was young and it was probably the late 60’s or early 70’s, watching TV at home before cable. The memory is blurry, but here are the features I recall: A line of lovely harem or slave girls in belly-dancer like outfits approach a large circular opening in the floor of the palace where a strapping man lifts them up, one at a time, and tosses them through the hole in the floor. I remember thinking it was rather lucky that they fell through the hole so cleanly, as it wasn’t much larger across than they were tall. The girls, one at a time (more than one I believe) then fall to their fiery deaths, screaming as they fall into the inescapable inferno below. I don’t recall if he tosses more than one through the hole or not.
Any clues?
“The Beast of Babylon Against the Son of Hercules”(1963)?
I think this is the scene.
