They go to some pretty incredible lengths too, A friend of mine and his dad own a stunt company that works explicitly with semi-trucks. Pretty much every time you see a semi in a stunt in a movie it's either my friend or his dad driving it. They will ship these semi's to foreign countries instead of film locally because the tax incentives are greater than moving entire production companies around the world.
Stargate Universe once, Atlantis twice, and SG-1 six times!
On the flip side, they use a lot of local place names and things, so it’s like a little in-joke when you notice them.
Also Toronto / southern Ontario.
If you see a city scene and there's streetcar tracks, it was probably shot in Toronto. See opening shot of this scene in Reacher s02e04:
It's all about the tax incentives.
Georgia started the race by offering very generous (at the time) tax credits to pull production away from LA and NYC. It worked for a while, and Disney filmed most of its blockbusters there for 15 years. But the talent was unwilling to move to Atlanta, so the actual cost savings weren't that great. This meant Georgia had a U-shaped movie distribution: very low-budget straight-to-streaming-back-catalog crap using entirely local cast and crew, or really big budget movies. Very few middle-tier movies shot in Georgia.
Then London decided to get in on the act, and offered a ridiculously generous film tax incentive that applies to almost all film costs, not just the "below the line" costs (those related to actual production expenses, like crew, equipment, etc). The only catch was that the studio had to publicly disclose the movie's budget, but the incentive was so generous that studios were willing to play along. LA survived the initial blow, until the dual writer and actor strikes drew attention to the UK's non-existent labor protections, but Georgia was destroyed by London's incentive because its tax incentive was the only reason for Hollywood to film there (and filming in Georgia is down over 80% from its peak).
So then California decided to make its film incentive competitive again, nearly matching London's film incentive. But the geniuses in the state legislature wanted to spread the love, so the most competitive credit is only available outside of LA. Epic Fail #1. Worse, there's a fixed and relatively low annual cap for the film tax incentive, so only a handful of productions qualify each year. Epic fail #2. As a result, productions that don't qualify for the CA film tax credit generally go to London (for the incentive) or Vancouver (because everything is cheaper there even without incentives).
P.S. I was part of the downturn-related layoffs, so I no longer work in film or anything film-adjacent anymore.
The failure of Camelot (1967) caused American filmmakers to shift exterior shots from studio backlots to authentic locations.[4] The film was widely criticized for its cheap look because it was obviously filmed on an architecturally ambiguous set against the chaparral-covered hills of Burbank.[4]1. City/region becomes a boom-town based on a new high profit-margin industry
2. As that region becomes more wealthy, labor increases in price, thus there is more incentive to seek labor/resources for that industry outside the city/region
3. City/region hollows out of middle-class level jobs for the industry, retains ceremonial labor and executive offices.
once people are arranging plane tickets/charters, then they fly to the best place financially.
But LA/Hollywood.gov priced themselves out of the market first.
Considering how much they did there it wasn't nearly as inconvenient as you would think. The school had a good process in place for controlling the chaos. It's still weird watching the movie and seeing my old library in it.
