This September the adaptation of John le Carré’s novel Tinker, Tailor, Soldier, Spy comes to the big screen – and it is a cast to die for.

Gary Oldman joins forces with Colin Firth, Tom Hardy, John Hury, Ciaran Hinds, Mark Strong and Benedict Cumberbatch in what promises to be one of the best political dramas of the year.

Set in the 1970s, Tinker, Tailor, Soldier, Spy finds George Smiley (Gary Oldman), a recently retired MI6 agent, doing his best to adjust to a life outside the secret service.

However, when a disgraced agent reappears with information concerning a mole at the heart of the Circus, Smiley is drawn back into the murky field of espionage.

Tasked with investigating which of his trusted former colleagues has chosen to betray him and their country, Smiley narrows his search to four suspects – all experienced, urbane, successful agents – but past histories, rivalries and friendships make it far from easy to pinpoint the man who is eating away at the heart of the British establishment.

Baghdad 1987, Latif Yahia (Dominic Cooper) is taken to see his former schoolmate Uday (also played by Cooper), eldest son to Saddam Hussein.

Latif is told that a great honour had been bestowed upon him: because of the great likeness between them, he has been chosen to be Uday’s ‘fiday’ – his body double. Trapped, tortured and fearful for the safety of his family Latif has no choice but to comply.

A chilling vision of the House of Saddam Hussein comes to life as Latif is forced to become part of Uday’s world, witness to the horror of his insane life of debauchery, excess and brutality.

A world entrenched in betrayal and corruption and an experience for which he almost pays with his life on more than one occasion.

The Devil’s Double is based on true events.
