Watch Thor: The Dark World

Thor: The Dark World takes place after the events of the previous films Thor and The Avengers, both part of the Marvel Comics film universe. Chris Hemsworth returns as Thor, the god of thunder and protector of the realm of earth who must do battle with the titanic forces of the universe one more time. The film opens with a flashback, before Thor's time, when his grandfather battled Malekith, an elf who sought to enslave the world with the dark forces of the Aether. Though Malekith lost the war, he and followers were locked away, and the Aether buried in a secret place. The movie then jumps forward to a celestial event called the Convergence, where all nine realms briefly align. Malekith awakens, reclaims his deadly weapons, and resumes a war forgotten for centuries.

Thor, along with the Lady Sif, the warriors three and a mortal woman named Jane Foster, along with Thor's brother Loki, must set aside their differences and defeat Malekith. If they fail then the dark elf will destroy all things good in the world, setting himself up as the ruler of a conquered and destroyed world made of darkness, suffering, and an endless sea of pain.
