upon the liquid surface of the questionable

Werner Herzog has an acting role in the wonderful film Incident at Loch Ness. The movie is a subtle indictment of the credulous. He's coaxed to board the monster-seeking boat. He does his best to join in the spirit of seriousness about the endeavor. He is uncharacteristically patient with the logic-dubious cryptozoologist. He even gets communally alarmed during an inexplicable episode. 

But...overall, our good man gives off an air of ennui and quiet exasperation about the whole enterprise. This performance -- the presence of the eccentric Herzog -- does extensive implicit damage to clanky forms of belief. His "ecstatic truth" has more to do with imagination-as-artform than with para-delusion.
