Bad Lieutenant: Port of Call New Orleans

My Son, My Son, What Have Ye Done
What they share
Both films are directed by Werner Herzog, and they both carry the raw, surreal mood tags, and they sit in Crime / Drama territory. If that's the register that drew you to Bad Lieutenant: Port of Call New Orleans, the second film will land in a comparable space — through a different lens.
What My Son, My Son, What Have Ye Done is
San Diego. Morning fog. A parakeet's squawk. An actor snaps, playing out Oedipal rage for an audience of none. Cops surround the house, his fiancée pleads, and a theater director fans the flames. Herzog's crime story plays like a very dark episode of *Columbo*.
