yeah, it definitely takes place in the modern day, the references and especially the wolf creek and scary movie 4. Although the prodco logos for The Weinstein Company and Dimension look like what they would’ve looked like in the 70’s, the year of the copyright on them is 2007, or mmvii. It’s a hyperreality that they’re putting us as an audience through. And Planet Terror too, it takes place after Death Proof or in between the two stories in death proof.
One, PT is definitely a post 9/11 film, pay attention to Bruce Willis’ kickass backstory, and two, pay even closer attention to the male D.J. over the car radio, early on in the film.
