If you ask me the whole "we're getting a Hollywood studio" thing is a bit over-hyped, and the Mayor is walking away with far too much credit because the timing coincides with her big annual speech.
The key thing is what what the studio is doing is pursuing a potentially rather minimal conversion of an existing empty building, rather than constructing an actual purpose-built building. From Skydance's standpoint it means a lot of money can be saved on getting an extra studio within an hour's drive of Vancouver, which
pretty much everyone wants these days anyways.
I mean, to start off, here's what the plant - which shut down only just last year - used to look like. Without the equipment (much of which was probably moved out/shut down when the plant did) it's a lot of big, empty space which would be very easily and inexpensively converted into a sound stage.
At the end of the day, these kinds of deals are possible anywhere in the region where there are big, empty warehouses and buildings. The studio is clearly moving in for reasons that have less to do with capitalizing on the potential of Surrey itself, but because a firesale deal showed up in front of their faces.
Think about it this way: If Pacific Newspaper Group decided to keep using the plant for a few more years rather than decide to contract out their services to a company in Annacis, Surrey might still be without a film studio.
