Factual error: Aetius' troops don't look anything like 5th century Roman soldiers. They are carrying a large rectangular shield, a pilum (a spear which was used for throwing) and a sword (gladius) on their right. This was typical for the Roman army until about the 3rd century A.D. In Aetius' time, the soldiers would have had smaller oval shields, a hasta (a lance used for stabbing and for fending off cavalry attacks) and a sword (spatha) on their left. Also, there would be an enormous amount of "barbarian" mercenaries in the Roman army (Goths, Vandals, even Huns.), so it was hardly a Roman army anymore. And where's Aetius' cavalry?

Flavius Aetius: Let's make a bargain here and now, a treaty of peace between your people and mine.
Attila the Hun: I think that's the first sign of weakness I've seen you show.
Trivia: In the movie, a soldier called Petronius unsuccessfully tries to murder the emperor Valentinian. The name "Petronius" was probably chosen because in reality the emperor was eventually killed by a senator called Petronius.
