The exodus has been given a name: runaway production. Adrian McDonald, a research analyst at FilmLA, a non-profit organisation that arranges filming permits, called the flight „staggering“. Of the 50 top-grossing movies this year, just four were filmed in California. In 1996, 20 of the top 50 were. On-location movie production in LA has plummeted 60% in 15 years. Not even Battle Los Angeles, an alien invasion romp, was filmed here.
