The Jar on AllMovie

Despite it's deciptive title, The Jar is not an adaptation of the Ray Bradbury story of the same name. It does, however, bear a slight resemblance to the Bradbury yarn, in that the jar of the title contains some unknown but fascinating power. Gary Wallace becomes a little too curious about the jar's contents, and before he knows it, he's a candidate for demonic possession. While all this is happening, the shapeless glop within the jar forms itself into.....AAAAUUGGGGHHH!!!!! Gore galore, and then some.
