I have no idea who made the movie.
I grew up in a very conservative small town in the deep South.
I doubt there were more than a dozen Jews in DeFuniak but the ones I knew of were typically very well liked.
Yes, anti-Semitism wasn’t a problem in the South, as much as the New York crowd would like to say so. The only ‘exclusive’ establishments in the south were those which catered to the Yankees.
