Corrected entry: At the start of the "Battle of Carthage", a man shouts: "Far away, in Zarma." Zarma is not the name for the land. It's Zama.
Corrected entry: Although many like to quote it, few have apparently read "Decline and Fall of the Roman Empire" by British historian Edward Gibbons. For it clearly describes a Roman general named Maximus Quintillian. He may or may not be the person portrayed in the movie, but there was a Roman general named Maximus who defeated the Germanians and was a favourite of Marcus Aurelius. He was killed by Commodus.
Corrected entry: One of the senators claim that "Rome was founded as a Republic". This is wrong, Rome was founded as a Monarchy.
