Continuity mistake: During the Warriors VS Ducks game, Charlie is driving down the rink and it cuts to a wide shot. You can see the puck is dropped and intercepted by a Warrior. In the next shot, Charlie takes a shot which the Warriors' goalie blocks. Charlie couldn't have gotten the puck back that fast, no matter how good he is.
Factual error: Throughout the entire Varsity/JV game, the Varsity team makes at least 20 penalties that aren't called. They also refer to a tripping call as hooking, even though the Varsity player obviously goes for the JV players ankles.
Audio problem: Right after the final buzzer, Julie the Cat skates out of the goal and pushes off her helmet, yelling "all right". She's smiling and her lips don't move.
Continuity mistake: When Portman tackles one of the varsity team's player through the glass, his helmet's attachment changes, in the face off, it's different than after the tackle.
Other mistake: When Portman is talking to Cole, the straps for his full face shield are missing, but after he checks Cole into the glass, you can see those straps attached to his helmet and face shield.
