MURDER WEAPON is a cheap and quickly-shot horror flick of 1989, made by David DeCoteau. It's a lot better than his other housebound horrors made more recently, such as the terminally bad '1313' series of the early 2010s. This one features a prominent turn for the often-naked Linnea Quigley; she plays one of a bunch of characters holed up in a house where a mysterious killer is violently dispatching most of the male guests. There are femme fatales here, silly over the top sex scenes, endless nudity, and one amusingly grotesque death scene inspired by a similar one in Friday the 13th. It's cheesy and trashy for sure, but for DeCoteau it's actually semi-decent.
