Ron Paul to the rescue. There ought to be a law requiring detailed, government approved, environmental impact statements for all Hollywood films shot anywhere other than a studio lot. Additionally reports should be required detailing the environmental efforts taken at the aforementioned studios to include the eco-friendly re-use disposition of all set materials.
I bet an on location movie is an eco-disaster with all the flying stars around, vehicles, gourmet bottled water, destroyed set material and such.
And I don't care what princess says, her make-up will look just fine under the new government mandated CFL set lights.
Pass a few laws like that and maybe they shut up some.
