The first full-length trailer for Agora is here, and it's pretty impressive. The film takes place in 391 AD in Alexandria, Egypt, when Christianity was sweeping the city-state. Hypatia (Rachel Weisz), the atheist philosopher, tries to infuse sanity into the situation as her student converts to the new religion. Believe it or not, for all its historical and educational elements, this movie looks pretty exciting, and has a cast full of actors we haven't seen before. Check it out after the jump.
