The Darkest Hour/In Time

A double bill of sci-fi thrillers. In 'The Darkest Hour' (2011), invisible alien invaders have seized control of the world's major cities, seemingly intent on sucking dry any source of electrical energy.

In Moscow a handful of young survivors, including Luke (Emile Hirsch) and Holly (Olivia Thirlby), struggle to get to grips with this unseen enemy and soon find themselves locked in a desperate fight, not only for their own lives, but for the future of humanity itself. 'In Time' (2011) is set in a near-future world in which time, rather than money, has become the ultimate currency.

With the ageing gene switched off, people don't age past 25, but there is a catch: they are genetically engineered to live for only one more year, unless they can afford to pay to stay alive for longer.

Will (Justin Timberlake), a young man from the wrong side of the tracks, is accused of murder after unexpectedly inheriting a fortune of time from a recently-deceased millionaire.

Forced to fight for his life, he takes the beautiful Sylvia (Amanda Seyfried) hostage in a desperate bid to escape from the powerful and corrupt police force known as the Time Keepers.
