- To Arrested Development, of all things, with the Duke of Weaseltown (WESELTON!) doing Lindsay Fünke's "chicken dance" during the ballroom scene.
- There was the unintentionally done example of Hans saying, to Anna, "We finish each other's..." and Anna replying, "Sandwiches!"
- And the Duke of Weselton shouting "She's a MONSTER!" (in regards to Elsa's powers being exposed) in the same manner that Buster Bluth cries out about his own monstrosity.
- A special mention to the names of Anna and Elsa's servants, Kai and Gerda, the names from the original story that the film is based upon.
- In the original story, Kai was jabbed by two shards of an evil magic mirror: one in his eye (making him see only ugliness in the world) and one in his heart (turning him cold and cruel). Anna is struck twice by Elsa's power — once in the head, once in the heart.
- Look closely at the truffles plate during the second verse◊ of "For the First Time In Forever" at Anna's line of "I wanna stuff some chocolate in my face!". They resemble the mountains from Sugar Rush.
- The Ice Palace, written by Norwegian author Tarjei Vesaas, tells the story of two girls, who seem to be Birds of a Feather, but the one shuts the other out, ending her life inside a vast ice construction. Coincidental parallell? Maybe, maybe not (in this book, the Ice Palace itself shuts the Elsa equivalent in, and when the rescue party arrives, everybody else is shut out; this is in deep contrast to Elsa shutting out everyone else in her life).
- Elsa's snow monster is nicknamed "Marshmallow" or "Marshmallow Man", possibly a reference to how he sometimes looks like the Stay Puft Marshmallow Man from Ghostbusters (1984).
- Oaken uses "ja" a lot in his sentences during his one scene, kind of like how in Fargo all the small-town Minnesota characters say this like a Verbal Tic.
- Anna and Kristoff escaping from Marshmallow via rappelling down the cliff bears reference to King Kong: Marshmallow pulls them up to yell "DON'T COME BAAAAACCK!" and then Anna and Kristoff cut the rope.
- Also from Marshmallow's scenes: his initial facial expressions when he ambushes Hans's search party bear resemblance to expressions that Sully makes when scaring Boo in Monsters, Inc.
- There's a scene in the town square where two men are arguing over the correct way to stack firewood: bark up, or bark down. This refers to a heated debate in Norway (part of Scandinavia, where the film is believed to be set) that was sparked the year the movie was released, after a 12-hour TV program on firewood aired. It included 8 hours of a live fireplace, and the network received dozens of text messages complaining about how the firewood was stacked. The complaints were split evenly between people who were upset about bark facing up, and those who were complaining about bark facing down.
- Throughout the movie, people keep calling the Duke of Weselton the "Duke of Weaseltown." It could be a reference to Home on the Range where one of Alameda Slim's guys, Wesley, is mistakenly referred to "Weasley."
- During "Let It Go", Elsa stubbornly declares "Here I stand...!". As a Norwegian monarch, Elsa shows she's familiar with Martin Luther's apocryphal "Here I stand. I can do no other." declaration.
- At one point in Frozen Fever, Olaf said "I can fix it!"
- There's a Mike Wazowski figurine on Oaken's desk next to the troll figurines.
- There's one point in "In Summer" where there's a sandwoman that's inspired by the Coppertone girl.
