There's a rumor going around that some of the humans in "Avatar" are CGI creations. Any truth to that?
''There are a number of shots of CGI humans,'' James Cameron says. ''The shots of [Stephen Lang] in an AMP suit, for instance -- those are completely CG. But there's a threshold of proximity to the camera that we didn't feel comfortable going beyond. We didn't get too close.''

What's the difference between normal 3-D and RealD 3-D? And is it better to see it in one format over another?
