 Filming in Morocco was hit by several problems. News of the  production was leaked out to the Daily Telegraph newspaper and it  published an article attacking the films prospect. As a result,  security was tighten and Ridley Scott had 4 bodyguards specifically  for him for 24/7. One of the trebuchets arm got snapped during a  night scene (its the one at the foreground right after Saladin said  "They wait") but no one got hurt. One of the siege towers was caught  on fire (shown in the final film) because one of the Molotov was not  cleared from the tower. Windy conditions at certain occasions made  filming difficult but it was a surplus and fans were not required to  create the dusty atmosphere.
