The first Avatar trailer is now online over at the Apple trailers section. It looks good, but not the kind of paradigm changing upgrade to movie-making he has been claiming. But then again, even the HD version of the trailer is not IMAX 3D, so if you want to see if he can really pull that off, be at one of the Avatar Day free showings for 15 minutes of the film at IMAX theaters all over the world. Since that is tomorrow, the 21st, you had best sign up for your tickets tonight if there are any left at your local IMAX.
