For a horror-comedy film about the alien-possessed, severed penis of a legendary porn star going on a homicidal sex rampage, this film seems to go out of its way to show almost no violence, nudity or sex. Had potential, but was too busy trying not to offend anyone's sensibilities to live up to it...
I'm pretty sure they didn't care if they offended anyone. The movie's about a killer penis.
I think they just wanted to show that you don't need excessive gore or nudity to make a horror film, even if it centers around people making a porno.
This is a concept that seems to get lost in a lot of horror films these days. People just want to put blood and guts everywhere, and huge tits right on the screen.
