When Doug and Kate play hockey, the Zamboni has just cleaned the ice. However, when they start playing, the ice is still dirty.
When Doug first meets Kate, he moves only a few steps towards her, as she is near the edge of the ice. In the subsequent wide shot, they are shown to be in the middle of the rink, some 40ft from the edge, even though they have not moved.
Before the free skate in the Olympics, as Doug is telling Kate he loves her etc, the same woman in a brown coat bumps into Kate two different times, from the same direction.
When Doug and his brother Walter are arguing about a letter from the Detroit Red Wings, near the beginning of the scene Doug lays down some hockey sticks, but when he sits down at the end of the scene, the hockey sticks have disappeared.
When Doug is giving Kate her Christmas present, her hair is in different positions in different shots even though she never touches it.
Theatrical type lighting and spotlights are not used in U.S. National or Olympic figure skating competitions.
In shots of the skates where the toe-picks are visible, they are the small toe-picks used by beginning and intermediate skaters. At the Olympic competition level, the toe-picks are much larger for use in jumping.
When Doug and Kate meet unofficially for the first time at the 1988 Olympics, the national anthem of the United States is heard. The only time a country's anthem is heard during the games is when an athlete for that country wins a gold medal, and then the anthem is only played for 80 seconds.
The Soviet Union did not officially compete in the 1992 Winter Olympics in Albertville. The USSR did not exist after December 26, 1991 and the Olympic Committee of the USSR disbanded on March 12, 1992. However, six of the fifteen former Soviet Republics did compete in the 1992 Winter Olympics as the Unified Team. The Unified Team's only other Olympic involvement was at the 1992 Summer Olympics in Barcelona. The Unified Team consisted of Russia, Ukraine, Kazakhstan, Belarus, Uzbekistan and Armenia.
Kate and Doug run into each other in the hallway of the arena where she is practicing figure skating and his hockey game is being hosted. Except that that would not have happened: the hockey and figure skating events took place in separate facilities.
It is mentioned in the movie that the Pamchenko is illegal, but the coach makes the comment "eh, legal/illegal..." and shakes his hand to indicate it depends on interpretation.
The first component of the Pamchenko - the "bounce spin", where the man grasps the woman by the ankles and spins her around - is a highly illegal move in amateur and Olympic competition and is only performed by professionals and/or in exhibition skating due to the high risk of head injury.
When Doug and Kate go out drinking after the Nationals in Chicago, they start doing Tequila shots and suck on lemons. You usually suck on lime slices when doing Tequila shots, these being supplied by the waitress. Since Kate was a non drinker it could be excused but Doug being a hockey player he would most likely know this.
The lead character has a game-worn Bobby Hull Chicago Blackhawks Jersey (#9) with Hull's name on the back; Hull last played for the Blackhawks in 1972, several years before NHL had players names on the backs of jerseys.
While they are in France for the Olympics watching the first US team skate, as the announcer is reading the scores in French. The scores on the board do not match the numbers the announcer is saying. He says cinq sept meaning 5.7, however the number in 5.8 or cinq huit. The number 5.7 does not appear on the score board even though the announcer calls it out.
During the first Nationals skate, Kate can be seen sitting on a foam "saddle" of some sort that was used to get a side-by-side action shot of her and Doug skating in sync.
Dolly tracks are visible behind the penalty box when Doug reveals to his brother what he has been doing.
(at around 1 hour 16 mins) Pamchenko twice mispronounces the name of Russian skater Brushkin (he says Bruskin) even though he is supposed to be a native Russian speaker.
The first time we see Doug Dorsey, he is in the Olympic village, in bed with a German athlete. As he is scrambling around, getting dressed, he states her name incorrectly. She corrects him by saying, "Ich namen Gita." Even in German, "I name Gita" is grammatically incorrect.
In the press conference at the Albertville Olympics, a photographer has a 500mm lens on his camera (it's the one with a small black disc in the middle of the lens.) This is the sort of lens you would use outside to shoot across a football field or nature photography, not inside.
