Revealing mistake: When they take a snapshot and it spins, then lands on the USA Today front page, like "Bombay Leads Team USA!" and they have his picture there... the words underneath the pictures all of the times they do this never match the story. They are just random articles that are talking nothing about hockey.
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.
Revealing mistake: In the final game against Iceland scene, there is a point where you can see that the people in the stands are actually cardboard cut-outs.
Factual error: At the end of the movie, they show a bunch of ducks flying. Those are not ducks, they are geese.
Other mistake: When Julie Gaffeny knocks the 2 Iceland players over, she is ejected from the game. But later, after Adam scores the goal, the Iceland player winds his stick up over his head and crushes him, yet he only gets a 2 minute minor penalty.
Deliberate mistake: At no time can a player on the ice play without a helmet. It may be legal in professional hockey, but never in youth league games, world championships or not (This happens when the goalie comes out of the crease and takes his mask off to shoot his "knuckle-puck", as well as the penalty shot in the first movie.)
Continuity mistake: Jesse and Averman walk off the platform twice at the conference that Iceland breaks up.
Continuity mistake: Team USA is competing in the Junior Goodwill Games, yet in one newspaper shot their picture appears under the heading 'Olympics'.
Continuity mistake: When Bombay and Stansson are playing one on one, there is one point when Stansson takes a backhand. In this shot, the blade on his stick is a righty. In all the other shots during this scene, he is a lefty.
Visible crew/equipment: When the old ducks meet their new team member and then the Zamboni is crashed through the boards, you can easily see a fog machine set up in front of the Zamboni.
Continuity mistake: In the scene near the end, during the final game, there's a woman in the stands with a white top on, but in a following shot the same woman is wearing a blue top.
Continuity mistake: The first time they play Iceland, Fulton takes a slapshot. When the goalie makes the glove save it hits him in the top part of the glove, where his fingers would be, but when he pulls his hand out the puck mark is in the middle of his palm.
Continuity mistake: In the Big Game against Iceland, the referee snaps the puck at center-ice to start the period. When he snaps the puck he is there, but one second later he is nowhere to be seen.
Visible crew/equipment: When the USA team is singing and skating down the streets and Coach Bombay is in the buggy, they all jump over the buggy and land successfully. But if you pause the movie you can see that the people skating are not actually the characters, they are the stunt doubles. Some of them are really funny cause they look nothing like the real characters.
Continuity mistake: There is an announcer's voice speaking as the camera moves in on Team USA's first game, against Trinidad. The announcer says that Team USA is leading 6 to nothing, but you can see the scoreboard while he's talking, and it says the score is 7-0.
Continuity mistake: In many of the game sequences players are simultaneously on the ice and on the bench. It happens most often with the kids that are not focused on so much, like Guy and Connie, but also sometimes with players like Charlie and Adam. Sometimes it's hard to tell if it is a montage and there has been enough time for the players to change, but at other times it's blatant. For example when Adam is hit on the wrist by the Iceland player you see Connie stand up on the bench and yell, but in the very next shot she's standing next to Adam asking if he's okay. And in the street hockey scene, when the puck is thrown back after hitting the car and Charlie scores a goal you see a reaction shot of the team celebrating. Charlie is visible at the bottom of the screen kneeling and cheering.
Continuity mistake: In the final game, Coach Bombay calls a time-out and supposedly that is where the switch of shirts between Russ and Goldberg takes place, so that Russ can fool the Iceland team and take his "knucklepuck" shot. However, when the timeout is called there is an overhead shot of all the Ducks, and you can see Goldberg in the center, facing Bombay, and Russ on the left of him (you can tell it's them buy the helmets and names on the shirts). After a shot of the Iceland team, it goes back to another overhead shot of the Ducks leaving to go back into play. None of the Ducks have changed position or barely moved, not even Russ and Goldberg, who need to move and trade shirts, which indicates that the shirt trade never happened.
Revealing mistake: During the penalty shot for Jesse Hall Number 9, notice he is right handed, as the camera changes.. the person doing the shot is shooting with a left stick, however when Jesse cheers, its back to right.
Continuity mistake: At the end of the final game when Adam gets ready to take his penalty shot they show a full body shot and it is clear that he is wearing standard CCM skate blades. There is a hole at the toe of the blade. When he starts his penalty shot, they show a close up of his skate kicking the puck and now he has Tuuk (that's the way you spell it) blades because there is no hole at the toe. Therefore, it's obvious a double is used to take the penalty shot.
