Most people often just take comics as entertainment and I myself am not one to delve too deeply when reading comics but this study from the history channel does gives us lots of room for insight.
I'm amazed that they use real historical figures to explain the though process of Batman/Bruce Wayne and the Batman's rogue villain gallery (Teddy Roosevelt among others). Christopher Nolan and Christian Bale also gives their own insights in this documentary.
This would be something for us to enjoy and past time. This documentary does look into Catwoman, unfortunately Bane wasn't mentioned at all. Overall it's interesting and makes one even more intrigued about the Batman mythos and Nolan's plans for his next installment of the Dark Knight
