“....Or, a different Hollywood created somewhere else ....”
This is what needs to be done. The original reason for Hollywood being where it is because of the weather. Easier for those 1920-era cameras to film, plus the easy access to western settings, good background scenery, etc. (Also then in that part of CA land was cheap!) No longer the case now on all those counts. As the Rutles would warble “All You Need is Cash!”
