Thor The Dark World 2013

Thousands of years ago, a race of beings known as Dark Elves tried to send the universe into darkness by using a weapon known as the Aether. Warriors from Asgard stopped them, but their leader Malekith (Christopher Eccleston) escaped to wait for another opportunity. The warriors find the Aether, and since it cannot be destroyed, they try to hide it. In the present day, Jane Foster (Natalie Portman) awaits the return of Thor (Chris Hemsworth), although it has been two years since they last saw once another.
