It's nuts that this 50 year old film still shocks. The CBT scene is well ahead of its time. I have had several subs refer to the stairs and how she descends them into her dungeon. I always thought that recreating the elaborate unfolding stairs was juice not worth the squeeze.

I heard legend of the director who was a major player in the NYC even into the 90s, but I never met him myself.

The movie is not realistic in how demure and obedient the french slaves are. I can assure you most are demanding and whiney.
