I would really be suprised if the CGI was finished at this point, as that tends to be worked on right up until the day before the movie gets turned in. That pyramid scene, with HUNDREDS of aliens, *has* to be difficult to animate, so I wouldn't worry if things don't look perfect yet. I'm loving the aliens so far, and I can't help but get the feeling that this is going to have everything that Alien: Resurrection was missing...namely the aliens.
I'm looking at a lot of these clips, and I really think that Anderson might finally have turned out a quality movie. If he *somehow* manages to screw this up, though (which I doubt), he's done for. The fans will hunt him down. But let's not think that way.
