O Enigma de Outro Mundo

You're stationed at an isolated outpost in Antarctica when you inadvertently discover a flying saucer type spacecraft beneath the frozen surface. Not long after you discover the alien pilot, trapped inside the ice sheet, looks like he may have been there for some time. Unfortunately, after recovering the entombed alien the protocols of containment are soon dispatched to a nearby bin and, before you know it, a rather excitable shapeshifting beast, who likes to take the form of bodies that have been turned inside out, and various other parts that should be internal and not external, is causing chaos and carnage and mayhem and disaster.

While not as good as the 1981 take, it is still a spectacular piece of masterful horror that continually delivers upon each subsequent viewing and provides some depth to the John Carpenter thriller.
