The Runestone

When an archaeologist uncovers an ancient Norse power stone, he returns with it to his New York City home. Too bad for the relic-digger, because it's not long before an evil spirit is projected from the stone into the archaeologist, turning him into a hairy beast. And too bad for the people of NYC, because this hairy beast goes on a vicious marauding spree that befuddles the local police. (official distributor synopsis)
