Frozen climbing to the top seems inevitable, as three months have already passed yet the inclination of audiences towards this film is still at an all-time high. Even its hit song "Let It Go" still gets significant number of views on Youtube.

According to Reuters, the film has sold $398.4 million worth of tickets at domestic (U.S. and Canadian) theaters since opening on November 27 on the eve of the Thanksgiving Holiday weekend. Foreign box offices have added another $674 million, for a global total of $1.072 billion, Disney said.

"Frozen," inspired by "The Snow Queen" fairytale, is the story of a Scandinavian princess who must reconnect with her sister, the Queen, who has the power of freezing anything into ice with her hands and accidentally sets off a long winter that is destroying their kingdom. Only finding true love will set them free over this gift or curse.

The previous animated-film box office champion was 2010's "Toy Story 3," which racked up $1.063 billion in sales, according to Boxofficemojo.com. Both films were distributed by Walt Disney Pictures.

"Frozen," which stayed in the top 10 films on domestic box office charts for more than three months, also has now become the 10th-largest grossing film in cinema history.

Really, what is the recipe behind Frozen's success and why can't fans get over it?

Of course, there are the songs, which can easily captivate the heart of young and young at heart, the moral lesson it imparts is simply timely, like when Anna asked for Elsa's approval on getting married with Hans, Elsa said "You don't marry someone you just met. To emphasize that statement, it was repeated by Kristoff, who then was still a stranger to Anna, when Kristoff asked for Anna's purpose on climbing the ice tower Elsa built. To put it simply, marrying someone you just met is not right no matter who you ask, exemplified from family and a stranger's perspective.
