Fan Casting Thor: The Dark World (2003)

In ancient times, the gods of Asgard fought and won a war against an evil race known as the Dark Elves. The survivors were neutralized, and their ultimate weapon -- the Aether -- was buried in a secret location. Hundreds of years later, Jane Foster (Christina Applegate) finds the Aether and becomes its host, forcing Thor (Brad Pitt) to bring her to Asgard before Dark Elf Malekith (Cirán Hinds) captures her and uses the weapon to destroy the Nine Realms -- including Earth.
