What? Skinny? If that is how it looks like in the movie than how it would be look skinny? Make it movie accurate and there will be no problemo. Arnold is not skinny (face or otherwise) in the movie and if HT make it just like in T2, well there will be no problemo just like I said. I gues I will wait for in hand pictures from you guys or I will wait for the DX version. I think this is the best choice.
They could slim him up a bit but that may throw off some of the other features he has. It could come out perfect however you always run the risk of what works for someone doesn't work for other people. There may never be a DX version it's speculation. I doubt anyone thought they would be a DX MJ and that it would be Superman, Rambo or Rocky.
