Continuity mistake: When Daniel and his mother are in their new apartment, Daniel goes over to the sink to fill up a bowl of water. The two items on the top by the sink appear in the first shot, then disappear in a shot from behind Daniel then reappear again in a shot from the front. (00:06:45)The-Immortal
Continuity mistake: When Mr. Miyagi saves Daniel from the Kobra Kai during the night of the Halloween dance, Mr. Miyagi flips Johnny to the ground and only strikes him in the stomach. The next morning, when Daniel and Mr. Miyagi go to Kreese's dojo, Johnny is seen with a black eye. Very hard to get one since he was never hit in the face.
Continuity mistake: When Johnny is walking away from Ali, the shot cuts to Daniel lying down on the sand, and there are two guys behind him, one with brown hair and a red tie around his head and a blonde guy. In the following shot after the line "Where did you find this guy," the two guys are now shoulder to shoulder with the guy in the yellow shirt. (00:13:35)The-Immortal
