The Thing

This week's third 'back to the past' also calls back the early 1980s with a prequel to John Carpenter's identically titled offering. Set in the Antarctic, a group of scientists discover a 100,000 year old spaceship with a sole occupant. Once thawed out, the occupant miraculously returns to life, and soon displays a neat trick: it can assume the shape, voice and memories of any person it touches. As a mysterious illness starts killing off the crew, they need to figure out who is human and who is not, before they all die.
