Thanks for the link Frank, however, I wanted to say that though they might be very informative, and I agree that those movies are not at all historically accurate--I would take these books with a grain of salt. The summaries on Amazon make me think that they are all written with Wikipedia as their main source. I was looking at possibly buying them...now I don't know. Has anybody read them and think they are worth buying?
I am not sure they are the BEST sources for helping students critically view films based on history. I discovered these while doing a search.
If you are interested in more scholarly work on this topic, I would, however, strongly recommend:
History by Hollywood- The Use and Abuse of the American Past; and Reel History: In Defense of Hollywood (both by Robert Toplin) Lights, Camera, History: Portraying the Past in Film Hollywood As Historian: American Film In A Cultural Context History in the Media: Film and Television
