Demonoid. 1981.
Samantha Eggar and Ray Jenson are in Mexico doing some cave mining when they find some ash, take it home in a box and the ash forms a severed hand that is cursed and causes a few problems and deaths, another easy going simple tale. Not quite a original plot using a disembodied hand, the makers went in a different direction with a story so give them a hand...or not for creating a new horror. This might leave you with more questions than answers at times, it does throw you into the movie quite quickly and in some parts does drag on then it paces itself back up. Stuart Whitman is the reasonable man of god until he faces evil and becomes a bit more of a believer. This is one i'd happily return to.
