Factual error: Another flag gaffe: The Canadian flag in the 1920s was either the red ensign or the Union Jack. The Maple Leaf only became the national flag in 1965.
Factual error: In at least two scenes, cars from the 1990's can be seen, despite the fact that the film took place two decades earlier. (00:50:00)
Continuity mistake: Toward the end of the movie when the Dragons are facing the Giants for the Pennant, Hammer is up to bat and get a hit. When you see him round first base, they show a picture of the dugout, where you will find him holding a large hammer. It's tough to be at bat and on the bench.
Factual error: During the Marshall-Xavier game the announcer refers to Xavier as the "Pirates", but Xavier's nickname is and was "Musketeers".

Factual error: During the movie, Doug watches video from the previous Olympic competition. The skaters are shown performing in a darkened arena lit by spotlights. Special lighting effects like this are not allowed in competition. All competitions take place in a brightly lit arena.

Factual error: At the beginning of the movie when all the guys are in the barber shop, a man is wearing a John Deere hat with the modern logo, not the one from 1976.
Continuity mistake: When the soccer coach is talking to the team in the class room she pulls down the world map on the screen. The camera flips back to the team for about 2 seconds and when the camera turns back to the coach the screen is pulled up.
Revealing mistake: In the fight between Julie and Ned, when she does the last kick to take him down, it's obvious that she doesn't actually kick him.
Continuity mistake: At the detective agency, while Bud and Lou are talking to the murderer, the description of the murderer comes over the police radio, and it states "5 feet 11 inches, weighs 165, blue eyes, brown hair, last seen wearing a felt hat and dark borwn overcoat". Then 15 seconds later Bud says out loud, writing on a piece of paper the description "5 feet 10 inches, weight 165, blue eyes, sandy hair".
Factual error: The third member of the Yankees with a prominent role in the film is Bob Cerv (roommate of Mickey & Roger). In the film, he is with the team from Opening Day. However, Cerv was actually acquired by the Yankees in May of that year.
Visible crew/equipment: When Ted is sliding down the hill after being chased by a bear, you can see a plastic sled on his back.

Factual error: During the final game against the Knights, whenever the score is shown on "TV", the Knights' score (home team) is shown on top and the Sharks' score (visiting team) is shown on the bottom. In sports, the visiting team's score is always on top and the home team's score is always on the bottom.
Suggested correction: In American sports yes, but not in other sports. In fact during the 1970's, NBA scores showed the home team score first.
