VIDEO: The Sci-Fi Machine That Made 2 Armie Hammers in The Social Network

This extended look at how Armie Hammer managed to play identical twins in The Social Network is more interesting than the average behind-the-scenes featurette for two reasons. First, we get to meet Josh Pence, who also acted out both parts for filming only to find out that his face would be replaced by Hammer. He seems to take the news like a real champ for the featurette, but still... Ouch. Second, take a look at this horrifying sci-fi geodesic dome contraption that Hammer enters so that lasers can copy his face! Welcome to the future! But, why couldn't they invent one that created better CGI breath?
