Paddy Considine is pacing along a metal gantry lined with padlocked storage containers as a cameraman tracks him from below. The actor is tackling a scene in a new television drama, Informer. The series, which starts in October on BBC1, will lift the lid on the most dangerous undercover policing carried out in Britain today: the murky job of hunting for potential terrorists.
"What do you think was in that suitcase?" calls out Considine, playing Gabe, a seasoned officer. "Just shy of 50,000 cash," replies Bel Powley, the rising young London film actress by his side for this filming session in east London. Her character, Holly, is new to the specialist terror prevention force and the duo have just tracked down money bound for Syria.
