Revealing mistake: In the fighting scene when Chozen has Daniel choking on the spear, before Myagi appears, the first person was standing on the deck to the left and throwing plants through the hut, but then Myagi comes and all of a sudden, he comes at him from the right. Somehow he made it from the left of Myagi to the right of him without anyone seeing him.
Revealing mistake: When Daniel and Kumiko are kissing and the storm is coming in, all a sudden the wind starts blowing hard. They act like they it was sudden. As a storm chaser for 28 years and weatherman, there is no way they would not have seen the storm coming even in the 80s. They would have known for days and also, it wouldn't go from calm to total destruction in a few seconds. Especially with a typhoon. They would have had days to prepare.
