Hi Raiyven.
Yeah, I think a cult film is one of those things that can cover possibly obscure, not always big box office films. But they have their passionate fans, beyond just being merely respected.
The 1977 film Damnation Alley, with George Peppard and Jan Michael Vincent battling for survival in a post apocalyptic world. Remember the scene where the guy gets eaten alive in the car with the mutant cockroaches?
