Egregious deviations from the book to the movie.

14. Mississippi probably had a better incentive package

About 20 years ago the US was losing a lot of film/TV production work to Canada and other countries because of cost. For example, The X-Files was shot in Vancouver.

So to lure that work back to the US, states started offering incentives, often in the form of tax credits. These incentives come with conditions though. The production usually has to use a high percentage of local crew and talent.

It can be an issue of location too. The novella that The Shawshank Redemption was based on was set in Maine but the movie was shot in Ohio. Why? They needed an abandoned prison to shoot in and that's where they found one. I have a friend that was an extra!

The cost and availability of studio space can be an issue for a film that requires a lot of sets to be built. There's a fairly new studio near Detroit, so they're getting a fair number of productions now that they would not have gotten otherwise. I know OZ the Great and Powerful was filmed there
