“Ghosts of Mars” (2001), directed by John Carpenter, is a sci-fi horror film set on a colonized Mars in the year 2176. The story follows Lieutenant Melanie Ballard and her team of Martian police officers as they are sent to a remote mining outpost to transport a dangerous criminal, James “Desolation” Williams. Upon arrival, they discover the settlement has been overrun by an ancient Martian spirit that possesses the bodies of the colonists, turning them into violent, primal warriors. As the officers and prisoners are forced to join forces to survive, the film delves into themes of survival, ancient evil, and the thin line between civilization and chaos in an unforgiving, alien landscape.
