Curvaceous Corpses (1995)

Brace and Kelly, a horror film directing duo who also happen to be lovers, have invited their catty cast of buxom starlets to a secluded mansion for the weekend to film their latest slice and dice masterpiece. The plot of their current production (also entitled "Curvaceous Corpses") revolves around an unknown assailant dispatching his unsuspecting female victims one by one using a gold snake necklace that delivers a deadly dose of curare poison through it's hypodermic fangs. Unfortunately for the ill-fated participants, the lines between reality and fiction become blurred once the bodies begin piling up on the set for real. Are Brace and Kelly hoping to set a new standard for snuff realism by actually executing their cast on video or will their obliviousness to the impending danger lead to their own demise in the ultimate twist ending?
