Revealing mistake: When the spear handle is protruding from Hector's shoulder, the area of the armor around the circular wound is clearly visible and it is in perfect condition. There is no tear in the armor whatsoever, around the wood, which would have been necessary to allow the wide spear tip to penetrate the armor and actually enter Hector's body as it did. (02:01:20)
Revealing mistake: During their fight in front of Troy's wall, Ajax shoves his weapon into Hector's face, causing Hector to fall back. In the next shot looking up, as Hector hits the ground, part of the wall is gone. There is even a bit of the crew's scaffold, visible behind the edge of the 'stone'. This particular piece of wall was never built as part of the actual set, so when it appears onscreen it is always CG, though in this shot the composite people did not complete it and at this precise angle it should be there. When the bodies are being collected (at the end of this battle), there is a good view of the wall intact. (01:20:00)
Revealing mistake: When Ajax slams the hammer end of his spear into a man, he has his shield at his back. The top arrow in the shield is bent at a 90° angle and as Ajax moves the top (plastic) arrow droops down and the bottom arrow actually flops around. While still in the same location, when he sticks his spear into the sand and pulls the arrow out of his thigh, the arrows on his shield are gone. (00:42:20)
Revealing mistake: When Paris and Hector ride back into Troy with Helen (in the chariot), Paris's cloak is held on the armor with blue laces complete with little plastic ends. Similar laces, in various colors, on others' cloaks are also visible in the film. Plastic was not invented until the 20th century. (00:28:00)
Revealing mistake: As the vast army of Greeks approach the shores of Troy, there is a close-up of Eudorus' legs as he makes his way to Achilles at the bow of the ship. As he walks, the very thick rubber soles with lovely, intricate, modern treads are perfectly visible on his old fashioned sandals with each step that he takes. Countless times the treads are actually identical on different character's sandal's soles. (00:35:55)
Revealing mistake: When Paris hits Achilles with the fifth arrow, as Achilles raises his right arm, the two round yellow stickers on both sides of his armor beside the studs, near the arm holes, are perfectly visible in this and the following two extreme close-ups. They are used to mark the bottom edge of the shot. Obviously they are gone in the previous and following shots. (02:28:50)
Revealing mistake: Achilles is hit with the final arrow that Paris lets loose, and he drops down to his knees. As he kneels on the grass his left ankle and foot are perfectly visible, and the arrow in his ankle/foot is unequivocally gone! (Visible on VHS.)
Revealing mistake: Just before Priam and Hector speak about Paris and Helen, the camera pans the exterior of the palace at the start of the shot. Later, when the camera pans up after Achilles dies, the same structures are visible, yet part of the stone buildings (beyond the statues that stand beside the grass) and a piece of the wall around the palace, are completely different. (This has nothing to do with camera angles.) (00:30:15 - 02:31:10)
Revealing mistake: After the Greeks break into the palace throne room, there is a close-up and consecutive wide shot of a particular white statue being pulled down with two ropes, then smashes apart on the floor and water. However, in the next shot of Priam, he turns around and as the camera pans out, the very same statue is being pulled down yet again, albeit with very noticeable differences in this take of the same shot. (Each of the unique statues in the throne room is visible in earlier shots.) (02:26:15)
Revealing mistake: Throughout the entire film, when soldiers are stabbing others it is blatantly obvious in numerous shots that the swords' blades or spear tips don't come anywhere near the armor or skin of the stabbing victim, and the 'victim' usually has either a delayed reaction to their wounds, or react before the weapons ever 'touch' them. (02:20:50)
Revealing mistake: After Hector pulls his sword from his shield, Achilles spins around and pulls his own from the underside of his shield. The sword is unsecured above his hand, not where it should have been, below his left hand on the handle of the shield, which was obviously done deliberately to ready the sword for the shot. (01:59:25)
Revealing mistake: When Boagrius falls after Achilles stabs him, in the close-up the two squares (gauze perhaps?) taped to his knees are clearly visible, when he hits the ground and his legs go up. (00:08:20)
Revealing mistake: When Ajax first arrives on Troy's shores an arrow penetrates his right thigh. The darker skinned latex material surrounding his thigh is perfectly distinguishable from his own light skin in the wide shots. Then after he breaks off part of the arrow, the rest which remains in his thigh disappears in consecutive shots. (00:42:35)
Revealing mistake: When the Trojans and Greeks first clash, after Menelaus' death, soldiers wearing kneepads are visible as they fight in the melee. (01:18:25)
Revealing mistake: When Priam and Hector speak about Paris and Helen, there is a shot from behind them where the city below is clearly visible, as they stand on the balcony. Later, when Priam sees the devastating fires he stands on the same balcony (the statues are visible behind him in the close-up), and the city's buildings, etc., are entirely different than the earlier shot. (00:31:10)
Revealing mistake: When Priam kisses Hector's face as the body lies on the pyre, the right side of Hector's face is visible and among the wounds that it sustained while being dragged, the cut under his right eye, which he had while still alive, is conspicuously missing. When the body is viewed from his left, as the flames flicker, the cut above the corner of his left eyebrow, which he also had while still alive, has gone astray as well. (02:14:50)
Revealing mistake: The long distinctive scar on Glaucus' left cheek drastically changes severity, shape, length, etc., in all of his close-ups. (00:57:20 - 01:54:45)
Revealing mistake: When Boagrius throws the first spear in the shot facing Achilles, Boagrius leans in to throw it and then stands straight just when the (CG) spear nearly reaches Achilles, who still has his shield at his side. In the next shot facing Boagrius the (CG) spear is still near Boagrius, who stands straight, and Achilles raises his shield for the incoming spear. This spear casts a (CG) shadow as it heads toward Achilles and when the ('real') spear tip penetrates Achilles' shield, there are other (CG) spear shadows on the ground heading toward Achilles - but NO spears. (00:08:00)
Revealing mistake: Odysseus normally has wavy/curly hair that reaches the base of his neck, yet just before Hector cuts Patroclus' throat, when Odysseus' helmet slips forward as he fights and the white cap is visible, his hair is very short and straight in back. It's also apparent earlier, when he visits Achilles in Phtia. (00:22:05 - 01:42:25)
Revealing mistake: When the soldiers' bodies are being collected in front of Troy's gate, after the battle, the pattern of the real stone wall (the set) on the left of the gate and all the soldiers that stand atop this wall, delightfully repeats, over and over, on the CG stone wall farther to the left. (01:23:30)
Answer: He doesn't yell any words, just an expression of anguish over his brothers death.
