Armando Iannucci discusses the combination of luck and judgement which led his film In The Loop to be released in the week that strikingly similar events unfolded in UK politics. The producer of TV spy drama Spooks explains how writers aim to predict events when planning storylines - for example, an episode about financial turmoil which aired at the moment when real banks were collapsing. He also reveals some of the programme makers' tricks of the trade.
