It’s called Agora, and it’s about Hypatia, who was a kind of non-Christian martyr, murdered by a religious mob. Here’s one account of her death:

And in those days there appeared in Alexandria a female philosopher, a pagan named Hypatia, and she was devoted at all times to magic, astrolabes and instruments of music, and she beguiled many people through Satanic wiles…A multitude of believers in God arose under the guidance of Peter the magistrate…and they proceeded to seek for the pagan woman who had beguiled the people of the city and the prefect through her enchantments. And when they learnt the place where she was, they proceeded to her and found her…they dragged her along till they brought her to the great church, named Caesareum. Now this was in the days of the fast. And they tore off her clothing and dragged her…through the streets of the city till she died. And they carried her to a place named Cinaron, and they burned her body with fire.

She’s definitely a wonderful subject for a movie, they’ve got a big name, Rachel Weisz, playing the leading role, and the film is done and looking for a distributor. No one wants to give it wide release. I wonder why? It could be that it’s badly made (not likely, since it was the highest grossing film in Spain for 2009), or it could be that a movie about an intelligent godless woman who is persecuted and slaughtered by a mob of mindless fanatical Christians with the approval of the church is a poor fit to the American political climate.
