Some excerpts from Werner Herzog’s Conquest of the Useless, detailing the making of his Fitzcarraldo in the jungles of Peru:
A fairly young intelligent-looking man with long hair asked me whether filming or being filmed could do harm, whether it could destroy a person. In my heart the answer was yes, but I said no. 
The thunderstorm held off all afternoon, but then descended far off over the rain forest, sweating and steaming, as if out there an enormous, violent rape were being carried out. 
This turkey, this bird of ill omen, is a pure albino, so it is quite a sight when it fans its great white wheel, spreads its wings, whose tips trail to the ground and puffs its feathers. Snorting in bursts, it launched several feigned attacks on me and gazed at me with such intense stupidity emanating from its ugly face. I pulled a feather out of its spreading rear end. Now the turkey’s sulking.
