So, you took the word of a woman in spite of the thousands of people that said the movie was accurate and true? Did she give reasons?
However, if you really want to go there we can tear down the historical inaccuracies of that movie if you want. It would seem that common sense would lead you to the fact that a movie is going to take a degree of "creative license" in their work even when they are trying to create a historical based picture. John Rabe, which I think is a better movie than Schindler's List is another movie about a German who tried to help those around him and would also be considered by "thousands of people" to be accurate and true, yet also has some glaring historical inaccuracies (the representation of the Panay particularly caught my eye).
But rather than rely on these "thousands" of movie viewers, if we are going to look at the inaccuracies in Schindler's List I suggest we look in more logical locations.
Some good places to look are:
Schindler's List by Thomas Keneally (the book the movie is based on)
Where Light and Shadow Meet by Emile Schindler (keep in mind that she had a bone to pick with Oskar since he was a womanizer and often cheated on her so take some of this with a grain of salt)
"The Real Oskar Schindler", by Herbert Steinhouse Saturday Night vol 109. (April, 1994), (Herbert interviewed many Schindlerjuden including Schindler's accountant Itzhak Stern. These interviews were conducted in 1949, but he could not find a publisher back then for his work.)
Oskar Schindler: The Untold Account of His Life, Wartime Activities, and the True Story Behind the List by David M. Crowe, Professor of History, Elon University.
Finally Schindler's Legacy: True Stories of the List Survivors by Elinor Brecher (She is a journalist who interviewed several surviving Schindlerjuden after the movie came out. A rather mixed bag with some of them pretty adamant over the inaccuracies in the movie)
In all you will find that Schindler did indeed save over a thousand Jews and I'm not taking anything away from that. However, he also was not the altruist and benevolent patron that is represented in the movie.
