The Ducks that appeared in the first film but did not return for this sequel are; Dave Karp (Aaron Schwartz), Peter Mark (J.D. Daniels), Terry Hall (Jussie Smollett}, Tammy Duncan (Jane Plank), and Tommy Duncan (Danny Tamberelli).
The scene after the first game with Iceland where Coach Bombay makes the team do sprints is based on Herb Brooks' 1980 US Olympic team when they tied the Norwegian national team in an exhibition game. The team skated for about an hour even though the rink manager had turned the lights off.
On the Duck's third goal in the finals versus Iceland, the announcer says Wu's name as he passes and they score. In the next scene showing the bench, Wu is clearly shown cheering.
