Other mistake: When Trash first comes back to life as a zombie there is a shot of rain falling and smoke swirling. The shot plays forward, then reverses for a second or two before playing forward again. The rain falls up and the smoke reverses direction.

Suicide: You think this is a fuckin' costume? This is a way of life.
Trivia: The actress who plays Trash is actually wearing a prosthetic rubber "crotch piece" during her strip scene (and subsequent scenes), which one of the producers insisted on, because he felt full frontal female nudity was "too much" for the film. Ironically, most of the shots of her are from a distance, and her under-region is hard to see, so in the end, the prosthetic was not really necessary. As confirmed in DVD commentary.
