Bad Lieutenant (1992)
Bent cops are one of Hollywood’s great themes (Serpico missed this list by a slither, if you were wondering). In Bad Lieutenant, Harvey Kietel is a gambling, crack-smoking pervert… and a policeman. Not the sort of man you’d ask for directions out of uniform. Although Abel Ferrara’s film came first, Werner Herzog’s 2009 “rethink” of Bad Lieutenant with Nicolas Cage is equally (un)watchable.
