Teased last week, New Line Cinema has now brought online the full new trailer for Bryan Singer's Jack the Giant Slayer, opening in 3D, 2D and IMAX 3D theaters on March 1. The action adventure stars Nicholas Hoult, Eleanor Tomlinson, Stanley Tucci, Ian McShane, Bill Nighy and Ewan McGregor.

Jack the Giant Slayer tells the story of an ancient war that 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, into the battle of his life to stop them. Fighting for a kingdom, 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.
