Toland is .. well, lets just say quite enthusiastic about the Nazis. The text is very detailed- he has done his homework, and sometimes has negative things to say about Hitler. For instance

'Dr. Carl Gustav Jung, the Swiss psychiatrist, had personally observed the two dictators and noted startling differences. In contrast to Il Duce, Hitler was like a robot.
"He seemed as if he might a double of a real person, and that Hitler the man might perhaps be hiding inside an appendix, and deliberately so hiding in order not to disturb the mechanism." '

But at other times what he has written borders on hagiography. Also, I noticed that Leni- Hitlers main film propagandist, actually signed this copy and wished him the best of luck. (Historically, she was a friend of Walt Disney, too. That doesn't speak well of Disney, or Toland. I mean- assuming you aren't a fan of Hitler, and think the eradication of all 'non-Aryans' is a bad idea.)
