A third promo for Star Trek Into Darkness has arrived this time focusing on Lieutenant Uhura [Zoe Saldana]. The clip features some pretty interesting new footage revealing some Klingons. Star Trek Into Darkness hits IMAX theatres this May 15th before expanding to conventional theatres on May 17th. Chris Pine, Zachary Quinto, Zoe Saldana, Karl Urban, John Cho, Bruce Greenwood, Simon Pegg, Anton Yelchin all return for some highly effective space drama & are joined by Benedict Cumberbatch, Alice Eve & Peter Weller. In the wake of a shocking act of terror from within their own organization, the crew of The Enterprise is called back home to Earth. In defiance of regulations & with a personal score to settle, Captain Kirk leads his crew on a manhunt to capture an unstoppable force of destruction & bring those responsible to justice. As our heroes are propelled into an epic chess game of life and death, love will be challenged, friendships will be torn apart, and sacrifices must be made for the only family Kirk has left: his crew. Bad Robot also revealed an intense new IMAX poster showing the menacing U.S.S. Vengeance firing upon the U.S.S. Enterprise. Hit the jump for the details.
