Continuity mistake: After Ajax's death, when Agamemnon shouts, "Forward!" as they charge, Agamemnon's two horses have very distinctive white markings on their faces. Then when Agamemnon and Odysseus (on the same chariot) retreat, after the cheering of Trojan royalty, in the close-up as Odysseus shouts, "Back to the ships!" the white markings are entirely different, and now both horses are actually wearing blinkers on their bridles to cover their eyes. (01:20:50 - 01:21:55)
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: 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: In the morning, while Achilles watches Briseis sleep, her arm extends way over the edge of the bed in the wide shots facing her, yet in the shots facing the doorway her position differs and even her hand doesn't reach the edge of the bed. (01:33:05)
Continuity mistake: When King Priam, Hector and the elder people are arguing about what to do about the Greeks, in the front view Hector is standing in the center of the edge of the pool of water, but when Priam stands up the shot changes to a back view and he is standing near the corner instead. (01:36:10)
Continuity mistake: When the Trojans attack the Greeks on the beach with burning balls of twine (or some similar material) at dawn, Hector is seen watching the carnage. He then starts to beat on his shield with his spear and his two generals begin to walk up to him from the rear. The shot cuts to Odysseus for about two seconds and then back to Hector. The two generals then again begin to walk up to him also beating their shields. (01:36:30)
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 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: The quantity of blood on Patroclus' neck, when Hector removes his helmet, changes between the shots. (01:43:55)
Continuity mistake: The cuts on Hector's face change and the one over Hector's left eyebrow actually changes direction, as well as other characteristics in many shots. When he shows his wife the tunnel, the top of the cut points towards the left side of his face, but when he stands at the gate and glances back at Helen, the top of the cut points up towards his right. (01:48:05 - 01:56:40)
Continuity mistake: When Hector says goodbye to Paris and kisses his forehead, the small decorative gold clasps and the very large clasp at the bottom of his hair are visible. Then when Hector says goodbye to Andromache and Scamandrius, the large clasp is a completely different one and the small clasps' positions differ. The clasps in Hector's, Paris', and others, hair change position in consecutive shots throughout the film. (01:55:00)
Continuity mistake: When Hector says goodbye to Andromache, before his duel with Achilles, in the shots facing Hector as they embrace his face is pressed onto Andromache's shoulder, but in the shots facing Andromache his face is higher up, beside her head. (01:55:15)
Continuity mistake: Just before Hector fights Achilles, he hugs his wife, and son. The boy is rather big in his wife's arms. A moment later, we see a wider shot of the family looking on, and the wife hands the boy to someone to hold for her. The bundle we see in her hands is very tiny compared to the baby she'd just had in the previous scene. (01:55:35 - 01:57:30)
Continuity mistake: When Helen is standing behind Hector before he goes out the gates to fight Achilles, she's very much on his left side (he turns and looks over his left shoulder at her.) But when he starts walking out and she's seen behind him, she's suddenly on his right. (01:56:30)
Continuity mistake: When Hector comes through the gate and confronts Achilles, the area around the two chariot wheels is clear. In subsequent shots large clumps of dirt and grass are in front and back of the two chariot wheels, which changes significantly throughout the rest of the scene, as well as the position of the wheel spokes. (01:57:10)
Continuity mistake: During Achilles and Hector's duel, in the wide shot Hector uses his shield to shove Achilles' spear tip down to the ground, beside his right foot while his left foot is way behind him. However, in the next close-up as the spear tip is still on the ground right behind Hector's left foot, his right foot comes forward to snap Achilles' spear. (01:59:20)
Continuity mistake: After Achilles stabs Hector with the spear, as Hector falls to his knees in the close-up, his greaves and shoes are entirely dusty/dirty - causing the dark sandals to be very light. However, as Achilles ties the rope around Hector's ankles in the close-up, Hector's greaves and sandals are now relatively clean and note the interesting pin-dot tread on the rubber soles of Hector's sandals. (02:01:20 - 02:02:00)
Continuity mistake: When Achilles spears Hector the blood on the spear handle differs in the consecutive shots as he stands, drops down to his knees, then falls over and when Achilles walks over with the rope. (02:01:20)
Continuity mistake: After Hector is speared, when Achilles thrusts forward with the sword, the tip of the blade makes contact on Hector's torso, under the large center medallion of the armor. However in Hector's close-up the blade is above the center medallion. (02:01:30)
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.
