The Snow Queen is one of Andersen's longest and most highly acclaimed stories.

When Elsa turns twenty-one, she is to be crowned queen of Arendelle.

Olaf is the friendliest snowman in Arendelle. He is innocent, outgoing and likes warm hugs.

When Hans proposes to Anna, Elsa objects, accidentally unleashing her powers before the court.

Elsa flees to the North Mountain, where she builds a palace of ice.

Micky Mouse makes a special appearance in Wandering Oaken's Trading Post and Sauna--in the form of a plush toy.

As a child, Kristoff was adopted by a female troll named Bulda.

Kristoff loses his sled after being chased by wolves. The new sled Anna gives him at the end of the movie looks like a major upgrade, with more room for ice and a cup holder.

According to Hans, three out of his twelve older brothers pretended that he didn't exist for two years.

HANS: We finish each other's--
ANNA: Sandwiches!
HANS: That's what I was gonna say!
