The entire 'Nanking' movie was stolen from another source!
Just stumbling across this tonight and doing minor research, it became obvious that the producer, Ted Leonsis, stole the premise and the entire movie and idea from Dr. R Joseph. All info, and the original video here:

It seems that Leonsis stole the idea in a (successful) attempt to profit from the low budget film on youtube.
Iris Chang (author: The Rape of Nanking) http://en.wikipedia.org/wiki/Iris_Chang
is quoted as saying:
"Beware of Ted Leonsis. Leonsis is the enemy of the martyrs of Nanking."
