So, this short clip is actually part of a (free PR stint) Twitter battle between Abrams and Snyder about both their upcoming movies. However, the thing that gets me is that this appears to be actual proof that Abrams is actually using as much in the way of practical effects as he can. And at the top of it appears to be a 1:1 Millenium Falcon.
Oddly enough, that actually excites me quite a bit. As much fun as it is to have CG this and CG that, you can usually tell it's not real and that occasionally actors are having a hard time working in a solid green screen room.
