A landmark work by a great film director
Due to making this film Leni Riefenstahl has been considered an immoral monster who glorified history's worst criminal. If only we all had the benefit of 20-20 foresight!
As others have noted here, in this film and "Olympia" Riefenstahl proved herself as so far the only female genius in the history of film. The undeniable power of this mesmerizing documentary is truly frightening.
I can't feel too sorry for Leni Riefenstahl losing her career due to making this film; the millions murdered and tortured by Hitler's regime suffered far worse. I do regret not being able to see the films she might have made later as a mature artist. It's as though the only films we had from Hitchkock were "The 39 Steps" and "The Lady Vanishes"; you would always wonder what he might have done later in life.
