The Ghastly Ones (1968)

A gruesome tale of revenge and bloodshed, from the Shock King of Staten Island, cult director, Andy Milligan. This super-cheap horror film story is set in an eerie Victorian mansion where a family has gathered for a will-reading. Three couples must spend the night there to inherit a fortune according to the will. Then they start dying one by one, as people are impaled with pitchforks, decapitated, dismembered, and have their throats hacked open with knives. There is a lot of disgusting gore including a scene where a hunchbacked cretin eats live rabbits.
