10 Movies That Gave Away The Spoiler Immediately

Frozen was a landmark film for the House of Mouse, completing the transition from the two-dimensional pictures of the company's pre-2010 releases, into a fully-fledged Pixar-esque three-dimensional model that retained the visual style of Disney's '90s and early '00s releases. It also made an absolute bomb at the box office and rejuvenated their core brand.

The musical feature is fronted by two princesses beset by magical forces in any icy kingdom, with a song for every mood and movement. And keen-eared viewers will know that the movie's opening song, Frozen Heart, contains more than just a salient warning to ice-based labourers.

Sung by a group of ice workers, Frozen Heart works a double shift, providing foreshadowing of the things to come and exposition of Frozen's plot. In fact, it tells the story of pretty much the entire film in a few short verses. The ice workers sing of icy Elsa's (Idina Menzel) magic, her inability to control it and the near-fatal ice she plants in Anna's (Kristen Bell) heart, and they plant the twin themes of love and fear within our minds before any of the action has taken place.

And you thought it was just a dumb kids' movie!
