Among those disciplined are Sergeant Bud White (a beefy and brush-cut Russell Crowe in a crisp Jack Webb likeness), a brutish shoot-first-and-ask-questions-later type with a thing for wife beaters, and "Hollywood Jack" Vincennes (a suavely cynical Kevin Spacey, whose light touch gives L.A. much of its oomph), a "celebrity cop" who serves as technical adviser to a Dragnet-like TV show -- when he's not setting up dope and sex busts of movie stars for scandal-sheet editor Sid Hudgens (Danny DeVito doing gleeful smarm).
