I seriously doubt that. Yes, there has been incentives started under Mike Foster's administration. However, the synergy is reaching the tipping point where it may be embedded in Louisiana long term.
I have a friend who deals in real estate. Many Hollywood workers are moving into the city. Many writers and producers are settling in the Garden District.
He says the demand for housing is so great in that area, that any house that goes on the market is usually sold the first day. He says many Hollywood types are paying cash, sight unseen for the houses.
There are also a number of large production facilities under development or being planned. The film industry is definitely becoming embedded in Louisiana.
Considering the bulk of what Hollywood produces, what that would effect is not proud of. a few years ago Louisiana was #1 in "Happiness" and 5th in importance of religion, and 41st in income. http://peacebyjesus.witnesstoday.org/Statistical_Correlations.html
Yet the Apostle was partly filmed there (i could criticizes it somewhat, but overall an exceptional movie) , and Duvall says in describing the making of it , You get below the Mason-Dixon line and you have some of the best music, culture, the two races, the literature, and it's so rich, so deeply rich in many things. So why not try to get it right if you're going to make a film of southern religion? That's what I wanted to do."
