Werner Herzog’s “White Diamond,” a documentary about Guyana’s majestic beauty as much as it is about a man’s Icarus-like obsession with flight, “seems motivated by a reverent, sober curiosity and a willingness to accept the irreducible mysteriousness of nature, in both its wild and its human incarnations,” says A.O. Scott in a review for The New York Times. Led by Graham Dorrington, an English aeronautical engineer, Herzog and his crew capture never-before-seen images of the tropical paradise. The film opens today in Manhattan and is the first of three documentaries by Herzog opening this month. It can be seen at the Film Forum over the next two weeks.
