Continuity mistake: In Thessaly, as the two armies face each other, the large branches all over the center battle ground change or disappear entirely, depending on the angle of the shot (note the cliffs on one side and the trees on the other side). (00:02:40)
Continuity mistake: At the very beginning of the film when the two leaders of both armies get off their horses, in one shot, the leader with the grey hair can be seen behind the horses walking up, yet when the camera cuts to another shot, from the other leader's perspective, he is now in front of the horses. (00:03:25)
Continuity mistake: During the opening scene, when Agamemnon is talking to the leader of the other army, after Agamemnon shouts for Achilles his head/body position differs between shots. (00:04:50)
Continuity mistake: A boy is sent to get Achilles, to battle what he later says is, "The biggest man I've ever seen." In the shot facing Achilles, as the boy tries to wake him, Achilles firmly grabs hold of the boy's right arm. However in the next shot facing the boy, Achilles has him by the neck to pull him closer. (00:05:35)
Continuity mistake: When Achilles arrives on the battle field in Thessaly, after being summoned by the boy, at the start of the shot as he rides passed the large army of soldiers, the cliff with its distinctive rock face is to his left. When he faces off with Boagrius, the area of cliff that was far in the distance in the opening shot is now substantially closer in these shots. (00:06:40)
Continuity mistake: The scars and scratches on Boagrius' face and body change significantly and some scratches disappear, between his first few close-ups and then when Achilles moves toward him. For instance, the scars on his chest are less severe in the close-ups when Achilles heads toward him. (00:06:45 - 00:07:45)
Continuity mistake: In the opening scene, just after Achilles has arrived, he begins to walk off from Agamemnon, and as the shot faces Agamemnon talking to the gentleman beside him with the white hair and beard, this man's position differs between shots. (00:07:25)
Continuity mistake: When Boagrius throws the first spear at Achilles, it hits Achilles' distinctive shaped shield. In the shot facing the back of the shield, their proximity differs, and the spear penetrates the shield in a completely different area than shown in the next shot, facing the front of the shield. (00:08:00)
Continuity mistake: When fighting Boagrius, Achilles tosses his shield with the attached spear, to the ground, the spear separates and lies beside the shield - which is face down, as Boagrius throws the second spear. However, when Achilles runs toward Boagrius their proximity differs, and when he stabs him the spear is gone and the shield is face up, but when Boagrius falls to his knees, the spear is back. (00:08:05)
Continuity mistake: The wound that Achilles gives Boagrius changes position from when he receives it in the close-up, where it is lower on his shoulder, to the close-up and back shots just before he falls, where it is closer to his neck. (00:08:15)
Continuity mistake: In Sparta, when Paris enters Helen's room, she faces him and says, "You shouldn't be here," When she turns around to face the wall, now there are short curls at her forehead and the hair curls at the sides of her face are now curlier and neater. Then when she is standing in front of Paris with her hands at her sides, in the two shots facing her, her hair goes from the front of her shoulders to behind, and the cute curl at her forehead is gone. This type of thing occurs throughout the film in consecutive shots. (00:11:40)
Continuity mistake: While still in Sparta, when Helen stands up after Paris rubs her neck, the strap of her dress on her right shoulder is closer to her neck when she removes the dress, than in the previous shot. (00:12:15)
Continuity mistake: When Paris puts the necklace around Helen's neck, Helen's hair over his hand changes between shots. (00:13:05)
Continuity mistake: In the opening shot when the camera pans in, as the ship sails back to Troy with Hector and Paris, the position of the sail and rigging differs significantly from the subsequent shot aboard the ship as Paris walks over to Hector. (00:14:30)
Continuity mistake: Aboard the ship going back to Troy, when Paris walks over to Hector he places his hands on the rail of the ship, and the collar on Paris' left side hangs off his shoulder, yet in the next close-up it's properly on by his neck. (00:14:45)
Continuity mistake: When Menelaus bursts into Helen's room, as he confronts the handmaiden about her whereabouts, Menelaus' hair curl is in front of his shoulder when the shot faces the woman, but not when the shot faces Menelaus. The same thing happens with Paris when he is with Helen, with Glaucus when he says goodbye to Hector, when Hector speaks with Lysander at the armory and so forth. Throughout the film all the men's hair in front and back - its position, neat or not, curls or not, etc., noticeably changes between shots. (00:15:50 - 01:54:45)
Continuity mistake: When Menelaus goes to see Agamemnon, as he walks toward his brother in the shot facing Agamemnon people stand aside and bow. In the next shot facing Menelaus some people appear or disappear from where they stood in the previous shot. The shadows differ as well. (00:18:05)
Continuity mistake: When Menelaus travels to his brother, Agamemnon, their positions differ when they speak and embrace, e.g., in the shots facing Menelaus two of his brother's fingers are on the cloak at his shoulder, yet in the shots facing Agamemnon his entire left hand lies on Menelaus' cloak. (00:18:25 - 00:19:20)
Continuity mistake: When Agamemnon says, "I always thought my brother's wife was a foolish woman," he is holding a whip in his hand that faces away from his right side. However, in the next shot the whip is closer to his chest, facing forward. Only visible on VHS and fullscreen DVD. (00:18:55)
Continuity mistake: In Phtia, as Achilles and Patroclus sword play, their positions as the duel with the wooden swords in relation to each other, and/or where they stand, change between shots. (00:21:20)
Answer: He doesn't yell any words, just an expression of anguish over his brothers death.
