A remake of 1951's The Thing from Another World, John Carpenter's The Thing updates that black and white movie (which was based on the 1938 novelette, Who Goes There?) with full color, widescreen and some of the best special effects in any horror movie (courtesy of FX master Rob Bottin). Following a group of researchers in the Antarctic as they discover the remains of a spacecraft and subsequently become infected by an alien life form, The Thing showcases some incredibly creepy moments, genuinely scary scenes, and a great ending
