Continuity mistake: After Priam kisses and welcomes Helen to Troy, they all walk inside. In the next wide shot, when Andromache (Hector's wife) steps forward to greet Hector, there is nobody to her left in front of the large column. However, in the next close-up there are two people who stand beside her, directly in front of that column. (00:29:30)
Continuity mistake: When the Greeks climb out of the 'Trojan' horse, the palm leaves lie differently on the ground around the 'Trojan' horse, in consecutive shots. (02:18:50)
Continuity mistake: As Briseis stabs Agamemnon in the neck, a particular part of his neck is visible in the first shot once the blade is in, just before he grabs her wrist. In the shot facing Briseis, the turned handle in her hand is further back on Agamemnon's neck than it should be to make the clean, straight, vertical wound below his ear. When she pulls the blade out, the wound is also positioned in the area that was visibly clear of the blade in the first shot. (02:27:40)
Continuity mistake: When Thetis says, "Like the ones I used to make you when you were a boy. Remember?" she puts her hand in the water to pick up the sea shell and the bottom of her right sleeve gets soaked in the close-up. However, in the next shot as she turns to face Achilles, that sleeve is dry. Her clothing material darkens greatly when wet, note the bottom of her clothing as she stands in the water when Achilles first walks over. (More noticeable on VHS.) (00:24:40)
Continuity mistake: When Eudorus tells Achilles about Patroclus' death, Achilles slaps him so he falls to the ground and gets sand over half of his face. Most of the sand is still there when Achilles puts his foot on Eudorus' neck, but when the foot is removed, there is hardly any sand left on his face. (01:42:20)
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)
Continuity mistake: After Achilles rescues Briseis from the men that were going to brand her, he brings her to his tent. The blood on her face differs in the wide shots, semi close-ups and close-ups, before she touches her face with the wash rag. (01:28:25)
Continuity mistake: While Achilles stands on Apollo's temple stairs and then when Hector climbs them, the position of the bodies lying on the stairs differs between shots. (This does NOT refer to when Achilles walks out the back of the temple, where there are no bodies. Note that the temple's front and back have different types of statues, stairs...) (00:44:00)
Continuity mistake: When Helen sutures Paris' leg wound, as he lies on the bed, the collar on his shirt fits round his neck properly, yet in the next close-up it hangs down off his shoulder, though he does not move. (01:24:35)
Continuity mistake: When Briseis stabs Agamemnon in his neck, in the shot facing the king he grabs her bare wrist, but in the next shot facing Briseis, Agamemnon grips her arm over her blue sleeve. Then after a brief shot of Achilles, Agamemnon grips her bare wrist again. (02:27:40)
Continuity mistake: On the beach of Troy, the exterior of Achilles' tent is seen in quite a few shots. In the nighttime exterior shot of the tent, just before Briseis asks, "Am I still your captive?" all the rope wound around the tent, the hides, etc., are all entirely different. Then the next time the tent is seen it looks like it did in the previous shots. (01:37:10 - 01:45:30)
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: On the Trojan beach, when the shields of Achilles and the Myrmidons are united in front of them, some of the arrows protruding from the shields disappear and reappear in consecutive shots. (00:40:25)
Continuity mistake: When Achilles and his Myrmidons line up on the beach and then bring their shields together, things located on the beach, surrounding them, ie large and small rock formations/boulders, wood, carts, etc., differ greatly from the previous and following shots. The way they form the tight group differs between shots as well. (00:40:25)
Continuity mistake: When the Greeks are at Troy's walls during the fight scenes the shadows cast keep changing direction. For example, when they charge Troy at night, in one shot as they run outside the city walls their shadows are cast to their right, but in the wide shot it's cast directly in front of them. (02:20:00)
Continuity mistake: The position of the three ropes that hang on the horse's head vary, between when it is first seen on the beach, when it is pulled into the city, and when it is finally placed outside Poseidon's temple. Because they are wrapped around its head, there's no way that they'd be able to move.
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: When Ajax fights the Trojans and then Hector, after the death of Menelaus, their positions and the positions of people standing and lying around them, change back and forth in many consecutive shots. During the Hector and Patroclus duel, the Hector and Achilles duel, and the other battles, the positions of duelers, soldiers - as onlookers, fighting or lying on the ground, change drastically between shots throughout the film. (01:19:10)
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: When Achilles pulls the sword out of Hector, the ground area is visible as he falls to the side, directly onto patchy dry grass. Yet when Achilles goes to tie the rope around his ankles, Hector now lies entirely on dirt. (02:01:45)
Answer: They didn't know the Greeks weren't bringing cavalry. The Greeks did use them and sometimes brought them by sea. It was there to stop a cavalry charge and to break up fighting formations.
