True to its title, Closed Circuit begins with a view of a London marketplace through a closed circuit camera. Gradually, the view changes from that of just one camera to two, then four, then eight, multiplying exponentially with each new conversation the cameras pick up from shoppers strolling through the street market. In this age of global terrorism, this is what life is like in one of the most wired-for-surveillance cities in the world. And director John Crowley's split-screen effect underscores how difficult it is to keep track of multiple information flows simultaneously. Just when you think you've gotten your bearings a truck pulls into the market, stopping illegally in front of one complaining vendor and occupying an increasing amount of visual space in each camera angle and therefore the entire screen. You don't have long to surmise something's wrong before the truck explodes, killing all of the innocent bystanders discussing their mundane life events minutes earlier.
