How Long Is “From Hell It Came”?

This horror movie, set on an isolated island in the South Pacific centers around a hapless native prince who receives a death sentence from the tribal witch doctor after he is caught associating with the American scientists who have come to check into the left-over radiation from an atomic bomb explosion. As the witch doctor stabs the prince in the chest, the young man swears that he will have his revenge. The shaman then buries the royal corpse upright in his coffin. Time passes and a terrifying tree stump grows from the prince's grave. With a fierce expression etched into the trunk, it begins to walk the island and exact its horrific revenge on everyone involved in his murder. The tree stump disappears when it steps into some quicksand and slowly slips back into the earth from which it came.
