Altough it has been years since I have seen Burden of Dreams, this movie has always remained etched in my memory as one of the greatest documentaries about the making of a film ( Fitzcarraldo). Although it is moving at a snail's pace, just like Fitz. it never ends to fascinate. It is almost as if the director wants the progression of time to happen in real time. The film depicts the insanity of Herzog's obsessive film making with passion and understanding. An absolute must see. As is Fitzcarraldo. On as scale of 1-10, this one ranks 11 (see "This is Spinal Tap")
