Quentin Tarantino and Robert Rodriguez's homage to exploitation double features in the '60s and '70s with two back-to-back cult films that include previews of coming attractions between them.
 
FUN FACT:  During filming, Josh Brolin asked Robert Rodriguez for a video camera so he could shoot his audition tape for No Country for Old Men (2007). He ended up having his audition shot with the million dollar digital camera they were using for the picture, directed by Quentin Tarantino, and with Marley Shelton reading the part of his wife in the scene. The tape was then scored and edited by Rodriguez before being sent to Joel Coen and Ethan Coen. Their first response on viewing the tape was to ask who lit the set.
