I did enjoy the 3D technology in Avatar, it was... "refreshing". Can't say the same for everything else about the movie, though 😛
Anyway, I would REALLY like to know how can Mr. Cameron "Aid" NASA's scientists with a 3D camera; is he an engineer? I wouldn't think that being a (good) movie director would be of much use for space travel, planet landing and so on.
Maybe he is just financing them 😉
...or maybe it is true what they say about NASA and the moon landing, that everything was staged, and they need a good director for the "First man on Mars" movie! 😛
