Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Continuity mistake: When Daniel goes sightseeing with the Japanese girl, they have a little running race to the castle. When they both stop running Daniel says "You cheated," and he is pointing at the girl with his right hand, but when the shot changes he is pointing with his left hand.
Continuity mistake: When Sato goes to see Miyagi, but he isn't there, Chozen destroys the dojo then tells his two friends to let Daniel go, and they throw him forward. His hands are not in the fighting stance, yet in the following shot he is now in his fighting stance with his hands at the ready.
Question: Throughout the film, are there a series of deliberate 'Back to the Future' references? I noticed two straight away - Daniel says 'If you put your mind to it anything is possible, you can do anything' which is repeated several times during BTTF. Also, when Daniel and Kumiko are at the dance, the song 'Earth Angel' can be heard. The song at the climax of the dance in BTTF. Are these deliberate, as BTTF was a year before this movie?Professor Lazarus
