Legend the Movie

"Once long ago, before there was such a thing as time, the world was shrouded in darkness.

Then came the splendor of light, bringing life and love into the Universe, and the Lord of Darkness retreated deep into the shadows of the earth, plotting his return to power....by banishing light forever.

But precious light is protected, harbored in the souls of Unicorns, the most mystical of all creatures.

Unicorns are safe from the Lord of Darkness, they can only be found by the purest of mortals. Such a mortal is Jack, who lives in solitude with the animals of the forest.

A beautiful girl named Lily loves Jack with all her heart. In their innocence, they believe only goodness exists in the world.

Together, they will learn there can be no good without evil....No love without hate....no heaven without hell....No light without darkness.

The harmony of the Universe depends upon an eternal balance. Out of the struggle to maintain this balance comes the birth of Legends."

Randomly, that Jack is mentioned as one of the purest of mortals before Lily is, is interesting and lends credence to the (mostly) abandoned idea that he, and not Lily, is intended to be the innocent one in the story.
