Plot synopsis:
“A historical drama set in Roman Egypt, concerning a slave who turns to the rising tide of Christianity in the hope of pursuing freedom while falling in love with his mistress, the famous philosophy and mathematics professor Hypatia of Alexandria.”

Rachel Weisz makes a lovely Hypatia. If they were more people like Hypatia at that time, people understanding the higher value of knowledge over religion and superstition, our civilization would not have regressed into the Middle Age.
