Continuity mistake: While Doug is in the maintenance room the French kid opens the door twice.
Continuity mistake: Doug and Tony are being interrogated by the Mars Mission flight crew. In two-shot, they're standing shoulder-to-shoulder with each other, no more than a few inches apart. When the shot cuts to a wider angle, Tony is suddenly several feet away. (00:10:00)
Continuity mistake: Jiggs goes back with a bag of grenades and a machine gun. He fires the gun, but when he is jumped on by the Trojan, the bag is gone. An object which may be a bag is lying on the ground, but is not the one he brought. No further mention is made of the grenades. (00:21:20)
Factual error: When Ulysses opens his mouth while speaking, modern dental fillings are in his teeth.
Revealing mistake: When Tony and Doug are captured by the Greeks, the lead Greek soldier points his sword to Troy. The "Troy" shown is a modern still picture of the ruins of the Greek Acropolis and surrounding structures, complete with a modern blue and white vehicle that looks like a bus in the lower left hand part of the picture.
Continuity mistake: The distance between Ulysses and Epeios goes from distant to close together as the shots change.
Factual error: The battle scenes show the Greek and Trojan cavalry troopers equipped with stirrups on their saddles. The stirrup would not be used until nearly 1,400 years later.
Factual error: This is one of two episodes in the series where a WW2-era German MP38/40 submachine gun was used by American forces (Master Sergeant Jiggs, in this episode) rather than an American weapon such as a Thompson submachine gun.
Factual error: When Doug and Tony recount the causes of the Trojan War, they mention three Roman goddesses - Venus, Juno, and Minerva - instead of using their Greek names - Aphrodite, Hera, and Athena.
Revealing mistake: During the final fight scene, Doug is struck by one of the guards and falls back against a rock. The huge boulder wobbles precariously when he hits it. (00:44:50)
Factual error: While firing their muskets at the guards as they rescue the Dauphin, Tony and Doug each quickly discharge their weapons twice without reloading. Muskets are one-shot weapons that required immediate reloading after firing.
Continuity mistake: As General Parker speaks with Biraky in the general's office, McDonnell has his arms folded, but the next shot when the phone rings shows McDonnell with his hands close together and a cigarette in his mouth.
Continuity mistake: After Tony and Doug's escape attempt, Col. Hruda enters the scene with his pistol drawn at waist level, but the next shot shows him holding the pistol close to his chest.
Continuity mistake: After Alexis gives Tony and Doug their IDs, Doug holds his document high with his right hand, but the next shot shows him holding it lower.
Continuity mistake: Doctor Biraky instantly moves closer to then further from Colonel Hruda as they argue over Tony and Doug being defectors.
Audio problem: In his closeup, Tony asks Alexis, "How did you get our names?", but his mouth does not move.
Continuity mistake: When Matthew and Jeremiah are fighting each other, a damaged empty barrel on a loading dock is knocked backwards, leaning against a wall behind it. The up close shots of the fight shows it upright, but the overhead views show it still leaning against the wall.
Continuity mistake: When Tony and Doug run to assist David and Matthew by the loading dock, the damaged barrel that was leaning against the wall behind it in previous shots is now closer to the edge of the loading dock.
