Quills

Terrific photography, a great cast (only Phoenix is his usual talentless self), and bundles of great irony to be found in the story. The Church, religion, hypocrisy, and self-righteous morals get a well-deserved drubbing. As twisted and perverted as De Sade may have been, he was an intellectual (which isn't commonly known), and any intelligent person will take his side when seeing what kind of people acted against him. His comments about God and religion are particularly nasty and to the point.

More accessible than "Marat/Sade" but a lot heavier, both dramatically and in content. Forget "Justine" and De Sade's other perverted stuff; I suggest you read his "Conversation Between A Priest And A Dying Man".
