A bit of trivia --- Did you know that The Vatican denied the makers permission to film inside the Holy See, so the production team had to build a scale replica of St. Peter's Square since Vatican officers banned the movie from being filmed in its grounds.

A brief synopsis from the book says that Harvard symbologist Robert Langdon is shocked to find proof that the legendary secret society, the Illuminati--dedicated since the time of Galileo to promoting the interests of science and condemning the blind faith of Catholicism--is alive, well, and murderously active. Brilliant physicist Leonardo Vetra has been murdered, his eyes plucked out, and the society's ancient symbol branded upon his chest. His final discovery, antimatter, the most powerful and dangerous energy source known to man, has disappeared--only to be hidden somewhere beneath Vatican City on the eve of the election of a new pope. Langdon and Vittoria, Vetra's daughter and colleague, embark on a frantic hunt through the streets, churches, and catacombs of Rome, following a 400-year-old trail to the lair of the Illuminati, to prevent the incineration of civilization.

A Robert Langdon quote from the trailer: The Illuminati did not become violent until the 17th Century. Their name means 'The Enlightened Ones'. They were physicists, mathematicians, astronomers. In the 1500's they started meeting in secret, because they were concerned about the church's inaccurate teachings. They were dedicated to scientific truth. And the Vatican didn't like that. So the church began to, how did you say it? Oh, hunt them down and kill them.
