Corrected entry: When Achilles saves the girl from the soldiers you can see that she is covered in scars and bruises. A night later Achilles is talking to her in bed, and she doesn't even have a slight cut or bruise on her face.
Corrected entry: Troy was a natural harbor, but the shots of the sea show waves breaking against the sand, which would indicate a beach. It would be impossible for the Greeks to have sailed their ships onto the beach, they would have been overturned by the changes in tide.
Correction: There are no tides in the Mediterranean Sea. It is too small and is choked off at the Straits of Gibraltar. It was common in Classical times (and even up to the present day) to beach ships during a prolonged stay on land.
Corrected entry: When Priam goes to Achilles to claim the body of Hector, he asks to have the body in order to perform the funeral rites and specifically mentions "let me place the coins over his eyes for the boatman". This references the belief of the Greeks that one had to pay the ferryman Charon to get into the underworld. However, at Hector's funeral, there are no coins on his eyes, nor does anyone place coins there as he is lit on fire.
Correction: There are coins on Hector's eyes. You can see them as the camera pans over his face.
Corrected entry: When Achilles and the Myrmidons land at the beach before Troy, they set up a testudo formation with their shields to defend themselves against the Trojan archers. The testudo formation was first used by the Roman legions, nearly a thousand years after the events depicted.
Correction: A tactic that can be worked out by one group can easily be worked out by another. It certainly cannot be said that the Myrmidons, who are noted as exceptional soldiers who would be perfectly capable of working out such a tactical move, could not have used that formation. It may have become commonly used in the time of the Romans, but that doesn't mean that it could not have been used by certain groups prior to that.
Correction: This is not correct. She had time to clean up and treat her wounds and as such are they are less visible but still there, most prominenately is the one across the bridge of her nose.
