In the past, we've wondered if James Cameron's project, Avatar, could really live up to the hype. Even the trailer, released last week, left us feeling kind of meh. But on Friday, Cameron released 20 minutes of 3-D footage in IMAX theaters nationwide, and it was instantly apparent why Cameron felt an Avatar Day was necessary, and why non-3-D footage of the movie doesn't convey how amazing the movie looks. Not that the movie is some groundbreaking piece of cinema: the storyline is a sci-fi take on Dances With Wolves (with a dash of Soul Man), the designs for the aliens and the military vehicles are old hat, and some of the dialogue is horrible. But when you're watching naked, blue versions of Zoe Saldana and Sam Worthington running around the jungle in high-definition 3-D, all of these worries melt away. Read on for a day-after description of the footage; I may be hazy on some details, but it's mostly the same as the footage that was shown at San Diego Comic-Con. And don't worry about spoilers, as a 3-D James Cameron informed us a the beginning that these are all from the first half of the movie.
