Funny dialogue
I have to admit I laughed out loud a couple times in this film.
The scene where the inmates are putting on de Sade's play about the Doctor and his young wife.
While one inmate simulates the Doctor going down on his bride, the one playing the wife says something like "What's this...such a wicked sensation
A feeling somewhere between shame and elation."
And the scene where the Marquis is relying on the inmates to verbally pass his story along to Madeleine through their cells.
He says something like "My prose...filtered through the minds of imbeciles".
In reality, the man whose very name spawned the word 'sadist' was reputed to be cruel, sick and depraved.
But this film depicts him in a fairly lighthearted way and I found it entertaining.
