Hector: All my life I've lived by a code; and the code is simple: Honor the gods, love your woman, and defend your country. Troy is mother to us all. Fight for her!
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 amusingly 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.
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, thus 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. As it turned out that beach was very erratic and one morning about 100 feet of beach had washed away overnight, leaving Greek ships teetering precariously on the edge of the bank with the missing sand.
