Anti-semitism is what made the Drefuss affair!
At least from what little history I can recall.
The review above the message board on the main page for this film (at the time of this post) says that the film completely sidesteps the fact of Dreyfuss' Judaism, although there was an outpouring of public anti-semitism in that time, and most of the vitriol hurled at Dreyfuss in the press and on the street was shaped largely by an anti-semitic mindset and frame of reference.
I haven't seen the film but would like to once I can get a copy through my inter-library loan, although the glossing over of what I addressed above is gonna make it hard to take seriously. However, Muni is a great actor and it won Best Picture (but so did Crash and Argo, so that distinction isn't so great anymore, not that it really ever was - 'How Green Was My Valley' beat 'Citizen Kane').
Thanks to anyone who comments.
