When I was a kid I hid by the couch while my uncle and his girl watched a spooker.  It was about a bunch of beautiful women models or ice skaters or something who went to a "retreat" in the middle of no where.  The place was like a castle or an old mansion on the edge of a lake.  To make a long story short the half naked hotties start getting bumped off one by one.  A seen in this movie that was so terrifying that I even remember today was a figure in a black jumpsuit skating across the ice wearing like an old lady mask  and a wig carrying a sickle.  The hottie sees her and tries to escape.  You see the figure get closer and closer and then raise its arm.  There is a spray of blood and then the cut seen is the hotties head laying in the snow of the bank of the lake or is being carried off by the figure, I do not remember which.  Does anyone remember or remember the name of this movie.  It scared the crap out of me as a kid and I have never seen other than that one time.

If it is, it's on DVD in the UK. Play and Amazon have it ready to go.

OK I got one...

An alien goes on a human hunting spree in the woods, his primary weapon are these manta ray like creatures that he throws through the air like a freesbee.  Most of the victims if I remember correctly are teenagers camping in the woods.  Eventually someone (local ranger or sheriff) finds his prey/victims are stashed in some fishing shack or something like this!!!

Anyone remember this movie???

Honestly it is pure B-rated sci-fi horror camp at its finest!!!  Clearly I haven't seen it in ages, but what I remember from my adolescent life, I thoroughly enjoyed!!!  Now I will go buy this classic piece of garbage!!!

Edit: Looks like this is either out of print or never made it to DVD!!!

Nice, that is what I remembered, great movie with a great cast!!!
