DVD: Bad Lieutenant: Port of Call – New Orleans (18)

Nicolas Cage's New Orleans cop, Terence, starts out as a cocky, sharp-suited, wisecracking law enforcer and spirals – via his crack and painkiller addiction – into a depraved sinner, lurching from one unruly scenario to the next.

Terence's giddy descent begins with saving a convict from drowning after Hurricane Katrina. This act of heroism wrecks his back and ruins his $55 Swiss underpants. Six months on, he's awarded a promotion for his bravery, but he's a changed man. He's, frankly, a menace; accosting teens for their drugs, assaulting elderly ladies, blackmailing football stars and imbibing a lot of drugs. He is supposed to be investigating a gangland massacre, but this is secondary to his addictions. Cage, in his best performance since Raising Arizona, is captivating and deliciously manic in this devilishly droll and scabrous Werner Herzog gem, which also features a singing iguana and a Val Kilmer cameo.
