It's 'Sherry and the Anus.'

Another hint....the girl who played one of the victims (a redhead) also played a corpse in a Clint Eastwood cop drama, had her own crime TV series, and starred in a cult zombie movie.

And another...the guy who starred in it is a regular in Brian DePalma flicks.

One more...Richard Laymon shamelessly ripped it off in his screenplay included in the anthology Screamplays. Fangoria even mentioned the similarities in its review of the book.

What is the Hills Have Eyes?

Nope, not The Hills Have Eyes. And it WAS released theatrically.

damn I cant for the life of me figure out what it is. It sounds like a couple of different movies.

The Hills Have Eyes was in the desert of California. And I'm not sure about the movie you are talking about DR.K

Okay....it was Josh Lieberman's Just Before Dawn. How about this, another slasher.....some kids go camping (as always) in New England, are warned to go home by George Kennedy, and are chased and killed by something that appears to be a were-bear (that's fun to say). The killer has a historical history, but to give that away would be to give away the title of the movie.

is it jack the ripper

I have no idea, but I just thought it was funny that you said "Historical History"
