Synopsis: An ancient war is reignited when a young farmhand unwittingly opens a gateway between our world and a fearsome race of giants. Unleashed on the Earth for the first time in centuries, the giants strive to reclaim the land they once lost, forcing the young man, Jack (Nicholas Hoult), into the battle of his life to stop them. Fighting for a kingdom and its people, and the love of a brave princess, he comes face to face with the unstoppable warriors he thought only existed in legend… and gets the chance to become a legend himself.
It's a shame the name was changed from Jack The Giant Killer to Jack The Giant Slayer, because now it's just a film about Jack and The Beanstalk. Before it would've been some kid killing a Giant. Darn.

Jack The Giant Slayer has an official release date of 22 March 2013.
