Dutch auteur Willem van Batenburg has been directing blue movies since porn’s awkward adolescence in the 1970’s. With dozens of films to his credit, including 1982’s legendary Pruneblossoms (1982), Holland’s first big budget porn blockbuster, van Batenburg has unrivaled insight into the development of erotic entertainment during the last three decades.

He’s just the man to be delivering tonight’s lecture, “Twenty-two Elements for the Making of a Pornorotic Lovescene.” In addition, he’ll read from his recent blue movie memoir It will all come up again, before dimming the house lights and screening a select few of his short but saucy films.
