Bruce Willis stars as a burnt-out cop whose ho-hum assignment to transport a     petty criminal 16 blocks turns into a nerve-shredding exercise in damage         control. Entrusted with crook-turned-star witness Eddie Bunker (Mos Def),        Officer Jack Mosley (Willis) sets out on what he assumes will be a short trip  to the courthouse. However, the casual drive quickly turns into a              heart-pounding confrontation with assassins, double-crossing cops, and other   thugs. "Raise(s) the banner for the tradition of the textured urban cop drama,   spurred by the action but made substantial by characters at crossroads"        Richard Donner---USA---2006---101 mins.
