First trailer for American Sniper

There's no flag waving in American Sniper's début trailer. No "Oorah"s or muscular posturing. Clint Eastwood hasn't taken to his director's chair to celebrate the most lethal sniper in American history - he's lying us down next to him and forcing us to soak up the tension.

Based on the autobiography of Chris Kyle - a Navy SEAL sniper with a record 160 confirmed kills out of 255 claimed - Bradley Cooper stars as the skilled sharp shooter on four tours of Iraq, tasked with protecting his brothers-in-arms.

Earning himself the name "Legend", Kyle struggles to balance his formidable reputation with the humble tasks of acting as a husband to his wife (played by Sienna Millar) and father to his son (Max Charles). With a cast including several ex-service men, this is set to be a tense ride.

American Sniper is set for a UK release on 16 January 2015
