Samantha Eggar's husband owns a Mexican mine which contains within it an ancient tomb housing a metal box with a severed demonic hand possibly possessed by the Devil himself. The hand attaches itself to Mr. Bains, in turn, possessing him. Each time the host is killed and the hand is severed it moves on to another human victim. The hand's ultimate choice for an owner is Eggar herself who joins forces with a priest(Stuart Whitman)to try and stop it. I have grown mellow over the years since writing user comments and really, really try to approach even the worse dreck looking for something positive from the experience. DEMONOID is one of those cases where I can not find one good thing to take away from it. The plot is preposterous, the severed hand gags are lame and laughable, and the actors attack their parts with an absolute seriousness which had to have been extremely difficult under the circumstances. Whitman and others doing battle with a severed hand trying to smother them is hard to watch without shaking your head in disbelief, and Eggar's fate at the end, the screaming, the swirling camera, broken glass table, it's the tip of the iceberg. For bad movie lovers, I think this junk will even bore them. It is an absolute slog to get to the end as a lot of nothing, other than the infamous severed hand crawling about, happens for long periods, but there are a series of decapitations which might amuse lovers of rancid cinema: a laser, train on railroad tracks, and a car door among other things. While Eggar hasn't necessarily starred in a ton of quality films in her career, DEMONOID would have to be considered the definite low point. Whitman, who I like a lot, doesn't have a prayer(pun intended)in this movie as the heroic man of the cloth who must use the power of Christ to combat the evil demonic hand. The funniest scene could be when the severed hand helps Eggar's husband Mr. Bain win at throwing dice in a Las Vegas casino--who knew a demonic hand had such luck.
