Dr. Glatt states that he might as well have "Security" on his sweater. The character is supposed to be an American, who would normally call it a jersey. Eugene Levy is from Canada, where it is commonly called a sweater.
Ross Rhea is seen reading a magazine article with a picture of Doug Glatt fighting Huntington of the Albany Patriots, yet this fight hasn't happened yet, since the Patriots vs Highlanders game takes place in the next scene.
After the Steelers score a goal in Glatt's first game in Halifax, you can see the scoreboard over center ice during the next face-off. The score is displayed as 0-0. Also, there is only one second off the play clock (it displays 19:59) although the game has been underway for some time.
Around 50 minutes, Doug has several cuts and bruises on his face, including a blackened left eye, split lip, and cut through his left eyebrow. In the next scenes, the bus ride to Quebec and the subsequent game, his face is completely clear again - no cuts, no scars.
When Doug and Eva go for a drive together and talk outside the car, a concrete building labeled "Manitoba Cold Storage" is visible in the background. Manitoba is at least 2,000 miles away from Halifax.
When the Highlanders face Quebec in Quebec City, the name of the arena is shown as the MTS Centre, which is actually located in Winnipeg, Manitoba. The logos for the MTS Centre and advertisements for Manitoba-based companies can be seen throughout the game. Quebec City's main arena is the Colisée Pepsi.
The two Russian players have the last name of Yakovlena, which is impossible since Russian surnames for men never end in -a. For instance, Maria Sharapova's father is named Yuri Sharapov. If anything, their last name would be Yakovlev or Yakovlen in real life.
Though the game shown at the beginning of the movie is between the Albany Patriots and the St. John's Shamrocks, the scoreboard displays the teams as Moose Jaw and Brandon. This scene was filmed at a Western Hockey League game at the Keystone Centre in Brandon, Manitoba. Also, the advertisements on the boards are for local businesses, including The Brandon Sun and Manitoba Telecom Services.
Halifax's home games were filmed at the PCU Centre in Portage la Prairie, Manitoba. In some shots, the PCU Centre logo can be seen on the scoreboard. There are also scoreboard advertisements for Meyers Norris Penny, which does not have offices in Atlantic Canada.
