Opening in 3D, 2D and IMAX 3D theaters on March 9, the adaptation of Edgar Rice Burroughs' classic novel tells the story of war-weary, former military captain John Carter (Taylor Kitsch), who is inexplicably transported to Mars where he becomes reluctantly embroiled in a conflict of epic proportions amongst the inhabitants of the planet, including Tars Tarkas (Willem Dafoe) and the captivating Princess Dejah Thoris (Lynn Collins). In a world on the brink of collapse, Carter rediscovers his humanity when he realizes that the survival of Barsoom and its people rests in his hands.
