You can read a review of the movie “Denial” at http://buffalonews.com/2016/10/20/overly-clinical-denial-puts-holocaust-denier-trial/
The following quote is from the movie review:
The film’s most emotional moment comes when Lipstadt and her legal team visit Aushwitz [Birkenau], a death camp not built to be one. As the discussion turns to proving the cyanide [Zyklon-B] used to kill Jews wasn’t for simply disinfecting against lice, Lipstadt drifts away to recite a prayer in Hebrew by the ruins of a gas chamber, while a raindrop that looks like a teardrop hangs from nearby barbed wire [fence].
I agree that this is a great scene, but it is a very deceitful scene. Would it have killed the producers of this film to have gone to Birkenau in the summer time, so that we could have seen the ruins of the gas chamber very clearly!
The following quote is also from the movie review:
Numerous sequences [in the film] of Lipstadt jogging or talking with Holocaust survivors are shoved between the trial sequences, and while these events may actually have transpired, they don’t push the plot forward at all. In fact, trimming these scenes would have led to a tighter script, allowing the suspenseful legal thriller hidden in this film to blossom more fully.
The point is that this film is very bad, and the scenes of Lipstadt jogging make it worse. I have never jogged in my whole life; I consider jogging to be bad for one’s health. I go for a walk every day, and that’s good enough for me. There will never be a movie about me, so I don’t need to jog.
