This 2004 video documentary by Werner Herzog makes a fascinating companion piece to his hair-raising Grizzly Man, even though his manipulations are more obvious.

A superb portrait of the dangers as well as euphoria that can come from chasing one's most treasured dreams.

Herzog loves to document humanity's perpetual struggle with nature, and in The White Diamond, the jungle -- sometimes makes sophisticated human technology laughably clumsy.

The White Diamond contains scene after scene of majestic imagery around Kaieteur Falls, but Herzog never allows his camera's gaze to dispel Nature.
