What a delightfully strange flick. It's at once a homage to Werner Herzog and a humongous Mickey-take at his expense. And like most Herzog films it whips your cerebellum around in its brain pan.
The scenario is a Herzog expedition to the Highlands of Scotland in search of the Loch Ness monster, or rather the director's attempt to get to the roots of the Nessie myth. It all spins out of control of course, at first because an ambitious producer Zak Penn, is trying to spice up the movie a little, (he hires a Playboy model as a sonar operator,) and then as the crew discovers there may be more to the Nessie story than first thought.
Herzog mocking Herzog and the whole idea of making documentaries. Priceless! (And now Penn and Herzog are up to it again in "The Grand.")
