Jon Heder 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.
Jay-Z and Kanye West used excerpts of the movie in the beginning and middle parts of their latest single "N****S In Paris" from the Watch The Throne LP: "We dance to one song and one song only", "It's provocative, it get's the people going!"
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.
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.
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."
In a website online, Johnny Weir comments on the fact that Jimmy and he 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. 'Jon Heder (I)' apparently made an offhand suggestion and was surprised to find that the costume was being created for him.
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.
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.
Although Jim Lampley, who cameos as the principle commentator at the ice skating competitions, has provided commentary on coverage of the Olympics for various networks, he is probably better known to viewers as HBO's anchor on the rather more macho sport of boxing.
