Ghost Rig (2002)

Editor's Note A crew of environmental activists snag an abandoned oilrig in order to air their protest to the rest of the world. When they discover a lost video camera, the crew learns that the rig's employees have all been taken over by an evil ghost which uses the bodies of the living to become animated. Once alive in human form, the entity leaves the body dead once it exits. Now the group's survival will depend on whether or not they can locate the evil spirit. What they don't know, however, is that the spirit is living in one of their own.
