Other mistake: In the semi-final where John Lawrence fights against Darryl Vidal, the female referee has major problems of what to do. When Lawrence gets his first point, the referee first raises her red flag (Vidal is wearing the red ribbon) but then swiftly changes her mind. And when Lawrence gets his third point, the female referee again incorrectly raises her red flag.
Other mistake: When Daniel, Miyagi, and Alli enter the tournament arena, they are stopped by a referee who says only fighters and coaches are allowed on the floor. They use the excuse of Ali being a translator to get her by. As they move forward you can see children in street clothes, girls with purses, old ladies, and others who are obviously not fighters or coaches.
Other mistake: When Daniel and his mother have to bump start the car, she shouts to Allie to pop the clutch. There is no tell tale sign of the car reacting to the clutch being dropped, and the sound of the engine starting is preceded by the sound of the starter motor turning as if the key was used.
Other mistake: The end tournament is supposed to be only the very best trained fighters in brown and black belts. Yet the majority of opponents against the Cobras are easily defeated, with weak tactics, unlike Daniel-san and the Asian guy, who actually use fight techniques.
