I always used to wonder why casting directors ever sent for Dougray Scott when they might just as well have used an old chest of drawers or a pile of deckchairs instead, but at last this gloomy Scottish actor seems to be coming into his own. Maybe his stint in Desperate Housewives kicked something loose, but he wasn't bad at all in BBC One's Day of the Triffids at New Year, and he's better still in this four-part gangster drama set in Manchester's terrifying criminal underworld.
