Exiled to Earth after his arrogance fans the flames of an ancient conflict, The Mighty Thor (Chris Hemsworth) of Asgard discovers the meaning of humility when a powerful old foe dispatches a destructive force to crush humanity. Only when the banished prince has defeated an opponent capable of crushing him in battle will he learn what it takes to be a true leader. Anthony Hopkins, Natalie Portman, Stellan Skarsgård, and Tadanobu Asano co-star in a comic-book adventure from acclaimed director Kenneth Branagh. ~ Jason Buchanan, Rovi
