Based on Lone Survivor: The Eyewitness Account of Operation Redwing and the Lost Heroes of SEAL Team 10, the book by Marcus Luttrell, Lone Survivor sees Mark Wahlberg (Lutrell), Taylor Kitsch, Eric Bana, Emile Hirsch and Ben Foster go after a wanted Taliban leader.

The mission is plunged into hot water when an unsuspecting child gets caught in the middle. The group are faced with a dilemma: kill the unarmed kid, who appears to be transporting livestock across the arid land, or let him go and risk him being an informant, essentially placing them – a four man squad – at the mercy of two hundred men.

Like many trailers, this one gives away a fair chunk of the plot; for instance, the kid is a little spy, and he does indeed draw attention to the presence and whereabouts of our understaffed US Navy Seal squad. In turn, they are involved in what becomes an escape mission, outnumbered and outgunned.

The difference for this film, is that it’s based on a true story, and it’s common knowledge that of the SEALs, all but Luttrell were killed in action. Will the inevitability of the film be dwarfed by the events that occur? We’ll have to wait until December 27th to find out.

The film is directed by Peter Berg, who began developing Lone Survivor six years ago after Universal bought the book and life rights for $5m. Since then, he directed 2012's Battleship – also starring Taylor Kitcsh – before making this one. We have seen the first cut of ‘Lone Survivor’ and it is soulful, gritty, tough, emotional and, quite frankly, remarkable,” Universal chairman Adam Fogelson said at CinemaCon back in April.
