Wow, did you miss the point. No comments on the 3D presentation compared to the IMAX version. The CGI was used to remov the wires from the stuntmen rigged to simulate 1/6th gravity. The filming was on an acutal (yes, real) set constructed on the lot next to where The Wizard of Oz was filmed. Most of the hardware was actual NASA equipment borrowed from museums and private collections.
