The White Diamond (2004)

Aeronautical engineer Graham Dorrington has built a teardrop-shaped airship to drift over the rainforest canopy of Guyana, and Herzog comes along for the flights near Kaieteur Falls. Dorrington still carries a heaviness from the death of cinematographer Dieter Plage, which gives the adventure real weight. Then the film wanders off in the best Herzog way: to the swifts that roost in a cave behind the falls, and to Marc Anthony Yhap, a local diamond miner who nearly steals the movie. A gentle, gorgeous one for nature lovers.
