When a producer is looking to film a production, they are looking to make the best of what they have on a limited budget.
Being on a limited budget, they look to find the best deals. Most producers shoot outside of Los Angeles because they get a better tax break somewhere else. These tax incentives allow them more freedom to use money in other places to create their masterpieces because they are paying less taxes or get a rebate after they spend their money in that state or country.
When the producer decides to shoot in that said state, he brings with him a budget where he will be investing money in the local economy. Therefore he is “stimulating” the economy by hiring local labor and purchasing goods and services in the area. It’s a win/win for the producer, he can pay his cast and crew more for their talent, the local economy and ultimately for you and I the audience who enjoy “the work!”
If the producer had a choice to shoot in Los Angeles or Vancouver and get the same “look” but could get more bang for his buck because the tax incentives or he is paying less in taxes, where do you think he’ll shoot at?
