Character mistake: After the male dragon has swooped by and destroyed Van Zan's convoy, there is a scene of Alex running through the fire up to him sitting there. After she asks "Where are the soldiers?", the subtitles for the DVD show the lines being spoken "One Pass. He flew over just once." while Van Zan is opening his hand up in a close up to let go of some ash. However nobody is actually saying these words. Turn the volume all the way up, and there is still nobody actually saying this. It's as if these lines were removed without the person in charge of the subtitles being told. Or were removed after he finished the subtitles. (01:11:27)
Character mistake: When newspapers are flashed on screen to demonstrate how the dragons have destroyed the countries, one of the headlines reads "Europes' capital cities in ruins." It should read "Europe's capital cities in ruins."
