It would probably look just like the poster on the right. And that's just one of the many very kewl "what-if?" scenarios that artist Peter Stults has come up with in "Movies from an Alternate Universe". Stults has brilliantly executed a series that... well, just try not to imagine Christopher Walken as the T-1000 when you see this rendering of Terminator 2: Judgment Day!
Great work Peter! And thanks to Kristen for directing our attention to this great feature :-)
