Deliberate mistake: When Jen Moo and Ching fling back the fire bombs thrown by Leong Kit, they set the rear ends of his students on fire. But since they were all standing facing front and dispersed around the altar, they would be most unlikely to be hit that accurately in that particular place.
Deliberate mistake: For most part, the actors (in the original version) talk in their native languages. But in many instances, the subtitles in the English versions have a different meaning than the spoken words. That is what I noticed in the Japanese dialogues, and most likely the Cantonese parts have been thus 'mistreated' as well.
