Troy (2004)

Visible crew/equipment: As Achilles' ship nears the Trojan shores, Agamemnon snidely asks, "What's the fool doing? He's going to take the beach of Troy with fifty men?" At the start of the next shot, as the camera begins to pan down, on the far right, just beside a person's (who is dressed in blue) head is a metal bullhorn (ie. used to give instructions to cast/crew, and which definitely doesn't belong in this time period).

Trivia: Due to the political situation in Iraq, the location for scale shots was moved from Morocco to Mexico, an ideal alternate choice with its broad beach. However, the rushed decision presented some obstacles. Coastal Mexico is an endangered turtle habitat, so to be granted permission to set up the Greek encampment and build boats on the large stretch of beach, the film crew implemented their own turtle incubation nursery, releasing a multitude of turtles while on location in Mexico. They also did not have an accurate idea of the physical conditions of that particular beach - it was unstable and 100 feet of beach washed away overnight, leaving Greek ships teetering precariously on the edge of the bank with the missing sand.

Question: What's the use of those sharp poles the Trojans put on the beach before the Greeks land? They're too large to be of use against infantry, and the Greeks don't use cavalry, and wouldn't be likely to use cavalry to storm the beach even if they did.
