To be fair, the film (or at least the depiction) is not without controversy. I went to IMDB.com - which is the authoritative resource for film - and looked up GWTW.
They give it an overall score of 8.9 which is virtually film perfection. Very few films are rated higher. But a caveat offered right up front starts with: “Whether we like the film, or not....”. Further down the line I see: “People don’t watch Gone With The Wind for the history...” before lavishing praise on the acting, sets, etc.
The point is the storyline itself reflects a regional bias and takes liberties with historical facts. It’s perfectly acceptable for fiction, but shouldn’t be taken for gospel.
The film is much more romanticized than the book. Mitchell had quite a few caveats about that. Especially the depiction of Tara, which in the book, is a simple farmhouse. That said, it is beautifully done with a superb performance by Vivien Leigh. I can’t imagine how many people ran to read the book after that and then checked out a history book on the subject. That is what art does: it educates, enlightens and entertains.
I use IMDB only to find out the facts of a movie - not it’s attitude towards a movie.
P.S.: what do you think is inaccurate in the film?
