This post is a reference from a reference. Stu Maschwitz talks about the Rodriguez List in his book the DV Rebels Guide, which is a reference to Robert Rodriguez' book, Rebel Without A Crew.
What's a "Rodriguez List"?
The idea is simple. You make a list of all the assets you have access to, things your friends, family, in-laws, extended family own that they would let you borrow for your film project. Cars, locations, props, etc. I love this idea, it's both efficient and frugal.
So, we're filming a movie called Dust, and within the story there's a scene in which a cop car parks in front of the main characters house. Well, how am I going to get a cop car? Enter facebook. Here I have three hundred or so friends, family, acquaintances who through a simple 'event' know that I'm making a movie, and that I'm looking for a cop-like car.
I ended up getting two cars (!) that were cop-like. A white Chevy Impala, and a white Chevy Blazer. After removing some hub caps, putting a cage in the back seat, adding an air-soft shotgun under the rear view mirror, and putting a laptop on the center console: we had a cop car!
