Lone Survivor hits cinemas this week, dropping Mark Wahlberg, Taylor Kitsch, Ben Foster and Emile Hirsch's hardened SEALs into enemy territory for a bare-knuckle war movie.
We caught up with director Peter Berg, who talked about the real-life story behind the film - which is based on the Marcus Luttrell's account of the failed Operation Red Wings mission in Afghanistan.
Lone Survivor opens in the UK on 31 January 2014.
