'Lone Survivor' depicts U.S. Navy SEALs comradery in Afghan tragedy --- (Reuters) - From shooting down a helicopter to firefights, film director Peter Berg spared no details to recreate a tragic United States Navy SEALs mission in Afghanistan in "Lone Survivor," an unflinching account of one of the worst losses of life in the history of the special operations force. -- The film, which opens in limited theaters in the United States on Christmas Day and wider release on January 10, 2014, is based on the best-selling book by Marcus Luttrell, the only man who lived to recount what happened during the covert June 2005 Operation Red Wings in which 11 SEALs and eight soldiers died. -- Two-time Oscar nominee Mark Wahlberg plays Luttrell, a medic and a sharpshooter who was one of a four-man team dropped by helicopter in the rugged mountains near Afghanistan's border with Pakistan on a mission to find a Taliban leader. - More, Patricia Reaney, at: http://www.reuters.com/article/2013/12/23/us-lonesurvivor-idUSBRE9BM0T820131223
