Continuity mistake: In the opening scene with Russell Crowe and his character's two sons, note the youngest boy's bangs. In the first take they are centered in a clump in the middle of his forehead, the scene cuts to Russell Crowe briefly and when it comes back on the boy, his bangs are all spaced out with gaps across his forehead. (00:02:20)
Continuity mistake: When Mary Jane and Skank are having sex they knock over a number of items on the stove, including a large bottle of red sauce. However, that bottle was not on the shelf or anywhere near the stove in the preceding shot that panned the stove area. (00:13:30)
Continuity mistake: When Johnny comes into the Mayor's Office to meet about his place in the Saturday Game, when he sits down there is a large black paper clamp/clip on the desk lying flat, but in the very next shot it is standing on it's side. The Mayor has had his hands folded through the scene and could not have moved it. (00:14:40)
Continuity mistake: When Marla's mother enters her bedroom to see why Marla is so upset, note the blue, yellow and white plaid blanket on the chair by the radio. In the first show it is hanging uneven with a portion folded back over, they cut to Marla for just a few seconds and when they cut back to the blanket it had changed and is now folded perfectly on the chair. (00:44:05)
Continuity mistake: During the scene where John and Donna are on the pond discussing the decision to build boards around the pond for sponsorship, it is snowing noticeably much harder when the camera is on John compared to when it is on Donna, where the snow is barely visible. (00:52:00)
Continuity mistake: At the end of the movie, when the Mystery team are consoling each other at the end of the game, the keeper is in the net, after he had been pulled and then stayed off when Mystery tried to score the equaliser.
Continuity mistake: When Russell Crowe first pulls in front of Hank Azaria his car's quite angled on the road as he gets out. When we see a wide shot after they finish talking, the car's now much straighter without anyone having gone near it.
Continuity mistake: After the game is over and the Mystery players skate back to their goal, in one shot Connor Banks' jersey, the back of it, has a lot of white from the ice and snow on the back. However in the next shot the back of his jersey is totally clean.
Continuity mistake: When the sports reporter guy gets drunk and get stopped by Russell Crowe, the Sherrif, he vomits by the side of the road. But when we next go to a long shot, no evidence of vomit can be seen.
Continuity mistake: At the end of the game against the Rangers, as the Mystery team is going for the tying goal, you see the Ranger goalie way out of position to the one side of the goal as Russell Crowe passes the puck back to Connor near the blue line. In fact, you see the goalie start his "dive" across the front of the net before Connor even receives the pass. We then see a shot from behind the net of Connor receiving the pass and that from this angle we can see that the goalie is in his normal spot in front of the goal, it then cuts to a shot of the goalie from the front where he is also in the middle of the net drifting back toward the goal in perfect position, but when Connor actually takes the shot, the goalie is back off to the one side of the goal trying desperately to dive across to make the save.
