Few movies have as troubled a production history as Werner Herzog's Fitzcarraldo. Principal photography was 40 percent complete when one of the movie's main actors, Jason Robards, became so seriously ill that he was forced to quit the production. After many production delays, the movie's other main actor, Mick Jagger, had to leave for a prior commitment (a Rolling Stones' concert tour). Virtually all of the film footage shot by this point was now unusable. After a year of filmmaking, director Herzog had to start over from scratch.
