Plot hole: The plot that a piece of the Roman spear that pierced Christ ends up in a hidden Mayan temple in the Amazon (which is nevertheless still full of gold etc.) makes no sense.

Factual error: Flynn says that the chamber in the Mayan temple is "an exact replica of their great temple of Teotihuacan." But Teotihuacan was not a Mayan city, but rather the hub of a separate civilization (themselves called the Teotihuacan). It was in central Mexico, hundreds of miles from the Mayan area in the Yucatan Peninsula.
Flynn Carsen: Professor Harris. I should've known he was evil. He gave me an A-minus.
