The late 70s. Drugs. Terrible rock music. Jack Palance. Andy Warhol. Even more terrible disco music. A nerd getting doused in baby powder by a semi-nude maid. I'd go on, but this frightening description is making Cocaine Cowboys sound more interesting than it actually is.
While it's got a lot of the trappings of your run of the mill blaxploitation film, it's more than just a Superfly knockoff starring the guy who wrote the theme from "Shaft." It's Truck Turner, and if you'll pardon my ridiculous movie critic pun, this Truck is no ordinary ride.
Transylvania 6-5000 is sort of the filmic equivalent of a late 80's Rod Stewart record- there's a whole lot of talent there, but you sure ain't gonna see it.
