Jon Heder broke his ankle while training to ice-skate.
1980 Olympian Lisa Marie Allen was not only the assistant skating choreographer on this movie, but she also appears in the film as the blond "Sweater Mom" who gets licked on the face by Will Ferrell's character during his Stockholm solo.
Will Ferrell made a cameo in Wedding Crashers as "Chazz Reinhold". His character in Blades of Glory is named "Chazz Michael Michaels".
According to the flags being raised, the four medalists at Worlds were from the United States, South Korea, and Sweden. South Korea has never medaled in men's singles at the World Championships, and Sweden has not medaled in that discipline since 1929. Furthermore, in the event of a first place tie, there would be no silver medal handed out, only the bronze, meaning that Sweden would have to suffice with a bronze and South Korea would have been left empty handed in fourth place.
All of the scenes at the World Figure Skating Championships were shot at the Los Angeles Memorial Sports Arena.
Many of the lifts Chazz and Jimmy perform are dance lifts, not pairs lifts. These are not illegal in pairs competition and have been performed by many pairs skaters in international competition, and therefore would not be something Scott Hamilton had never seen before. (Unless Hamilton has never watched ice dance.) Despite what Coach claims, there is no specific lift named a "dance lift". Rather, the term refers to a variety of lifts done in ice dancing.
Will Arnett and Amy Poehler (who play siblings in the film) are actually married.
The van Waldenberg name was taken from the family name of one of the writers.
The writers claim that "88.773% of Will Ferrell's dialogue is improvised or changed in some way to suit his persona."
The coach in the movie is played by Craig T. Nelson who also starred as Coach Hayden Fox in the sitcom "Coach."
The hotel that Jimmy and Chazz stay in when they're in Montreal is actually a famous building called "Habitat 67", designed by Moshe Safdie in honor of Canada's centennial. In reality it is not a hotel, but a privately owned condominium complex.
Chazz Michael Michaels' skating style was inspired by the skating style of Elvis Stojko.
For a hint to where Coach got the idea of two men ice dancing, note the stained plastic artwork in the kitchen of his cabin.
In a website online, Johnny Weir comments on the fact that Jimmy and him have the same style. The peacock outfit was actually based on Weir's swan outfit from the 2006 Winter Olympics. Both of the costumes incorporated the skaters' arms as the necks and the hands as the beaks of the birds.
Ben Stiller was considered for the role of Chazz Michael Michaels but he decided the character was too much like other roles he had played.
Real skaters making cameos include, Sasha Cohen, Scott Hamilton, Peggy Fleming, Brian Boitano, Dorothy Hamill, Nancy Kerrigan, Kyoko Ina, Yuka Sato, Jamie Sale, and David Pelletier
Due to problems with the 6.0 system, Chazz and Jimmy are forced to share a gold medal, a reference to the 2002 Olympic Winter Games figure skating scandal.
Stranz and Fairchild plot to injure Chazz "below the knee and above the ankle", references the attack on Nancy Kerrigan prior to the 1994 Olympics.
The Iron Lotus is a parody of the Pamchenko from The Cutting Edge.
The "loophole" at the center of the movie does not actually exist. International Skating Union regulations state that a pair team on the senior (Olympic) level is made up of a man and a lady (note that "lady" is the official terminology for a female skater).
Both Jon Heder and Will Ferrell learned how to ice skate for the movie. They trained extensively with Michele Kwan's coach Sarah Kawahara.
Directed by the same duo who are responsible for the Geico "Caveman Commercials."

'Jon Heder (I)' spent two years in Japan as a Mormon missionary, and learned to speak Japanese fluently. He showcases this talent during the press conference when he responds flawlessly to a reporter's question posed in Japanese.
Jon Heder came up with the idea for the peacock costume after watching Johnny Weir's "Swan" routine. He apparently made an offhand suggestion and was surprised to find that the costume was being created for him
During the opening of the movie, when Jimmy is discovered skating as a child, the song that is playing is "Time to Say Goodbye (Con te partiṛ)", a duet by Sarah Brightman and Andrea Bocelli, which was also featured during an ice skating routine performed by Katarina Witt in Ronin (1998).
At the Sex Addict's Anonymous meeting, the "Sex Addict's Prayer" (as shown on the prayer card) is: "God, Grant me the serenity to not have sex with my friend's girlfriend, the courage to go home tonight without having sex with my friends girlfriend, and the wisdom to walk away from my friend's smokin' hot girlfriend."
Although it is only referred to subtly throughout the film, the filmmakers intended for the characters of Coach (Craig T. Nelson) and Jesse (Romany Malco) to be understood as romantic, as well as professional, partners. Some indications of that include the stained glass window in the kitchen showing the Coach and Jesse together (surrounded by hearts) and the triangle-shaped rainbow ornament visible on their shelf during one scene.
