Trivia: The scenes at the Black Gate were shot at the army munitions training ground because of its wide, flat, desert type landscape. Before the shoot, the land had forty years worth of demolitions, land mines, mortars, grenades, etc., lying all over. The government asked the army to clear and dispose the ammunition for the filmmakers, but due to the soft ground many could've remained undetected. When the crew arrived for the shoot, an army officer lectured them and showed them different types of munitions to warn them of the possibility of finding more on the site, as dirt was kicked up during battle sequences. There were bomb disposal people surrounding them and sure enough shooting halted as things were discovered and cleared. The cast and crew were told that if they strayed from the designated areas and lost limbs, the army was not responsible.
