Now here's a film that will have plenty of people sitting down on the sofa this evening. Sky Atlantic brings us the premiere of Manhunt, a documentary exploring CIA investigations into Osama bin Laden and the al-Qaeda terrorist network. The film tells the story of a group of all-female analysts who recognised a potential threat to the US years before the September 11 attacks but struggled to convince their superiors of the danger, and examines how the agency's role has changed in the last decade. If you liked Zero Dark Thirty then you'll probably love this.
