German director Werner Herzog begins work on his 1982 epic “Fitzcarraldo” but soon runs into serious setbacks, from casting problems to his own stubborn refusal to use special effects. After having to reshoot much of the film because the lead actor was recast, his crew must then haul an old-fashioned steamboat over a mountain using manpower alone. With a resolve bordering on insanity, Herzog struggles to realize his vision, vowing to see the film completed — even if it leads to his undoing.
