My favourite of his is Lessons of Darkness. It is fairly uncategorizable; it can hardly be called a documentary.<p>The film roams across the oil fields of Kuwait, left burning after the first Gulf War. Steadycam helicopter shots glide over landscapes set to the haunting music of Mahler, Arvo Pärt and others (there is, of course, some Wagner). There&#x27;s little narration; the few fragments are abstract and prophetical. The whole film is a rather disturbing tone poem about a futuristic, burning apocalypse. It&#x27;s fantastic.<p>The White Diamond [2] is also great. The subject matter (an attempt to fly a special air balloon to study the rain forests of Guyana) is interesting, but takes second or third place to the beautiful photography of the forests and the superb, eerie music of Ernst Reijseger, whose film music was released as the album Requiem for a Dying Planet [3], and a couple of Herzogian moments as he gets sidetracked by a weird native (whose philosophical monologue may have been scripted by Herzog) and a waterfall.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Lessons_of_Darkness" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Lessons_of_Darkness</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_White_Diamond" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_White_Diamond</a><p>[3] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=FS1wabo4rXk&amp;index=2&amp;list=PLCOIBtqK1bke_WhtnZMLbOYRjUl6ib8me" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=FS1wabo4rXk&amp;index=2&amp;list=PLC...</a>
