Alfonso Cuaron's engrossing dystopic nativity takes place in a world of mass infertility caused by a global flu pandemic. The last child born, an 18-year-old referred to as baby Diego, has just died and the world is descending into chaos. Britain in 2027 has become a police state littered with internment/concentration camps (filmed in Bexhill on Sea of all places), it is a country where dissent and civil unrest is met with brutal suppression. Clive Owen plays a booze-soaked former activist who now pays the bills as a bureaucrat - until that is, he is abducted at gunpoint by dissidents and given the opportunity to smuggle a young refugee out of the country - or take a bullet. Why such secrecy and death threats? The refugee is female and is the first female to fall pregnant in 18 years. The child is a symbol of hope in desperate times and the dissidents and government will do anything to possess it. This film is as bleak a vision of Britain's future as could be and the slate grey framing and grimy, rundown urban settings brilliantly convey a nation on the precipice of anarchy and chaos. Strong supporting cast features Julianne Moore, Chiwetel Ejiofor, Michael Caine and Clare-Hope Ashitey. Children of Men - Monday at 9.00pm on Sky Cinema Brits. Photo: © 2006 Universal Pictures.
