The Karate Kid Part II (1986)

Revealing mistake: When Daniel and Kumiko first see the storm coming near the end of the film, the wind outside is blowing the trees sideways. They open the door to run out and the camera shows what is outside. The trees there are not moving.

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.
