Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Other mistake: In Roy Hobbs' last at bat of the movie he takes the 1st pitch for a called strike (confirmed by closed captioning). The 2nd pitch is called a ball. The Pittsburgh manager then decides to change pitchers with the count at 1-1. The relief pitcher's 1st pitch is fouled into the press box making the count 1 ball and 2 strikes. The 2nd pitch from the relief pitcher is swung on and missed, and should be strike 3. Hobbs stays in the box and hits a long fly ball foul and hits a HR on the next pitch. Roy Hobbs should have struck out. (02:06:20 - 02:12:05)
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.
Other mistake: When Happy hits the ball in the alligators mouth, he is on the complete other side of the lake where the gator is located, and there is a crowd of people blocking his view, but somehow he can still see through the people and over the lake, to notice the gator taking his ball.
Other mistake: When Miyagi throws Mike into the light switches, the lights go out but the switches never change position.
Other mistake: During the one game playoff against the Yankees, the runner Taylor picks off at first base has the same number as the batter who had just struck out. Also, the number they both wear has been long since retired by the Yankees and therefore no player could ever wear it again. Again, in the first game against the Yankees, the first base coach also has the same number, making it three Yankee players with the number 37.
Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.
Other mistake: After Guy gets hurt in the warriors/ducks game, the scoreboard is shown. It says that there is 15 seconds left in the third period, when it is really the second period.
Other mistake: When Malcom X walks out on to preach before he gets shot, you can clearly see the podium with the bullets in it and chipped from the guns before he gets shot.
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: During the dinner party scene, Carl is going gopher hunting. The shot of him approaching the tree shows it's daylight in the background, when the previous shot showed it very very dark out.
Other mistake: When Don and his father are driving home and Don's father throws his ring out the window, Don gets out to search for the ring and you can see wet marks on his shins from kneeling on the wet road. However, he hasn't knelt down yet. It must have been from previous takes. Also, when he gets up after kneeling down, his jeans are dry. (01:01:50)
Other mistake: When the NASCAR pit crew starts working on Herbie at the barn, they initially pull a bunch of parts and tools from their racetrack trailer. One man is carrying a distinctive VW-only wheel rim, which would definitely not fit their regular NASCAR car. The decision to race Herbie had just been made, so they would not have been carrying VW spare parts yet. Nor could they have pulled one of Herbie's wheels yet since they were still carrying the jack to the barn.
Other mistake: In the championship game, the Yankees batter hits a foul ball when they score their winning runs.
