Trivia: The scene where Fiona impressed Shrek with her loud burp was added to the film courtesy of Cameron Diaz. Diaz gave such a loud belch after drinking some Coke during recording that it gave the filmmakers the idea for the gag.
Trivia: Shrek took more than four years to produce. One of the reasons it took so long was that Chris Farley had been cast as the voice of Shrek, but he died in late 1997 from a drug overdose in the middle of production. His lines had to be re-recorded by Mike Myers.
Trivia: In the scene where Lord Farquaad is in bed, watch as they pan up to him, you'll see the bear skin rug on his floor is actually the Momma Bear from The Three Bears. Baby bear can actually be seen crying in the huge gathering outside Shrek's cabin.
Trivia: There are 36 unique locations in Shrek - more than any other computer-animated film.
Trivia: A fairy godmother named Dama Fortuna was originally included in the movie, but was cut out in the beginning of the movie's production. However, Dama Fortuna will be included in 'Shrek 2' (2004).
Trivia: Mike Myers actually does the voice for two characters: Shrek and one of the Three Blind Mice.
Trivia: Cameron Diaz, Eddie Murphy, and Mike Myers never met during the recording for the movie.
Trivia: Mike Myers actually read opposite his wife Robin when recording his lines for the climactic love scene at the end of the movie.
Trivia: When Shrek and Donkey arrive at Dulloc and are about to see Farquaad for the first time, Shrek says something about Donkey being in the right way for a smacked bottom, that is a tribute to Austin Powers who is also played by Mike Myers. If any of you have seen the music video "Beautiful Stranger" by Madonna, Austin Powers says nearly at the end of it that Madonna is going the right way for a smacked bottom. He also said the same thing to someone behind the scenes while recording his Shrek lines as he was frustrated at the direction he was being given.
Trivia: Conrad Vernon, who voices the Gingerbread Man, was originally just a member of the production staff, and he was used to feed lines to John Lithgow, as Lithgow never acted with Mike Meyers, Eddie Murphy or Cameron Diaz. They ended up liking Vernon's performance enough to make his role official.
Chosen answer: This is most likely because "broad" isn't too nice of a word, and children of any age could watch the trailer. Parents wouldn't want their children to copy inapropriate language, obviously.
